Abstract
Description
Technical Field
[0001] The present invention relates to fabrics and household care compositions comprising specific graft polymers. These graft polymers can be used in fabric and household care compositions, preferably in laundry detergent compositions. Background Art
[0002] Initiatives have been proposed in various countries to ban microplastics, especially in cosmetic products. In addition to the ban on insoluble microplastics, there is a strong dialogue about future requirements for soluble polymers used in consumer products. Therefore, it is highly desirable to identify new and better biodegradable components for such applications. This problem is particularly severe for polymers produced by free radical polymerization based on a carbon-only main chain (a main chain that does not contain heteroatoms such as oxygen), because a carbon-only main chain is particularly difficult for microorganisms to degrade. Even industrially important free radical-produced graft polymers with a polyethylene glycol main chain show only limited biodegradation in wastewater. However, the polymers described in the present invention are preferably produced by free radical graft polymerization and provide enhanced biodegradation performance compared to the prior art.
[0003] Polyalkylene oxides are important polymers with a wide range of applications. They have been widely used as a basis for the production of graft polymers, and such polymers are commonly used in various consumer formulated products, including household cleaning compositions and cleaning compositions for other uses.
[0004] Similarly, graft polymers in which vinyl esters are grafted onto polyalkylene oxide polymers (such as vinyl acetate-grafted-polyethylene glycol) are known polymers. Their use in the detergent field and many other application fields is also known. However, those polymers lack biodegradability or at least suffer from very limited biodegradability.
[0005] However, after use, a significant portion (and possibly all) of such consumer products will ultimately be rinsed away, and if they cannot be removed by biodegradation or other means in a sewage treatment plant, they may flow into rivers or the ocean.
[0006] Therefore, biodegradability is becoming a crucial property, not only in the detergent field, because biodegradable polymers can avoid the problem of continuous accumulation in the environment.
[0007] In some countries / regions, according to current legal regulations, such problems will no longer be permitted, and even if the relevant provisions have not yet come into force, it is expected that the legislative process will be completed in the near future.
[0008] On the other hand, the functional properties imparted by such polymers are equally crucial, as they not only enable efficient cleaning but also reduce the use of cleaning additives during a single cleaning process (which is just one of many advantages), thereby saving the materials used and thus avoiding environmental pollution. These special polymers can also achieve cleaning effects at low temperatures, in short time periods, and with low water consumption, and are thus key materials essential for environmentally friendly cleaning processes.
[0009] Therefore, it is crucial to provide biodegradable polymers for the detergent field, which can solve the environmental pollution problem without affecting the cleaning efficiency - because a reduction in cleaning efficiency would instead lead to a more serious environmental burden than the inevitable pollution.
[0010] A well-known such polymer is the graft polymer of vinyl acetate on PEG6000, with a weight ratio of 60% (VAc) to 40% (PEG), which is known for its beneficial cleaning and whitening effects and is widely used in liquid washing formulations (liquid detergents and gel detergents) and solid washing formulations (such as washing powders and laundry sheets).
[0011] Polyalkylene oxides have poor biodegradability, and their biodegradability gradually decreases as the molecular weight increases from several hundred grams per mole to up to several kilograms per mole. Even more so, the biodegradation performance of graft polymers based on such polyalkylene oxides is usually even worse, which may be due to the grafting effect.
[0012] Prior Art on Graft Polymers
[0013] US2019 / 0390142 relates to a fabric care composition comprising a graft copolymer, which can consist of: (a) a polyalkylene oxide, such as polyethylene oxide (PEG); (b) N-vinylpyrrolidone (VP); and (c) a vinyl ester, such as vinyl acetate. However, US 2019 / 0390142 does not disclose the graft polymer required currently.
[0014] WO2020 / 005476 discloses a fabric care composition comprising a graft copolymer and a so-called processing aid, the graft copolymer having a polyalkylene oxide composed of ethylene oxide, propylene oxide, or butylene oxide as the main chain (preferably polyethylene oxide), and N-vinylpyrrolidone and vinyl ester as side chains grafted onto the main chain, and the ratio of the main chain to the two monomers needs to meet specific requirements.
[0015] WO2020 / 264077 discloses a cleaning composition comprising a combination of an enzyme and a polymer, such compositions being suitable for removing stains from soiled materials.
[0016] The present disclosure discloses a so-called "suspension graft copolymer" selected from the group consisting of: poly(vinyl acetate)-g-poly(ethylene glycol), poly(vinylpyrrolidone)-poly(vinyl acetate)-g-poly(ethylene glycol), and combinations thereof. However, the graft polymers defined in the present invention are not disclosed.
[0017] US31816566 discloses so-called "lactone polyesters" graft polymers and their blends with PVC. The lactone polyester is a homopolymer of ε-caprolactone or a copolyester of ε-caprolactone and ε-alkyl-ε-caprolactone. No polymers prepared with a combination of lactone and alkylene oxide as the graft substrate as described in the present invention are disclosed in the prior art. The lactone polyesters described in US31816566 are grafted with ethylenically unsaturated monomers, and in a long list, "vinyl esters of aliphatic acids" are also mentioned, which lists vinyl formate, vinyl acetate, and vinyl propionate. Twenty-two examples demonstrate graft polymerization reactions using acrylic acid, butyl acrylate, methyl dimethylaminoacrylate, styrene, acrylonitrile, and methyl methacrylate as the only monomers actually used, and all examples use only a single monomer for grafting without using any monomer mixtures. Only one example (Example 12) uses vinyl acetate as the monomer and poly ε-caprolactone as the graft substrate (i.e., a graft substrate without any alkylene oxide), with 200 grams of the main chain and 30 grams of vinyl acetate, that is, the addition amount of vinyl acetate based on the graft substrate is 15% by weight, equivalent to 13% by weight of vinyl acetate based on the total polymer weight. US31816566 does not disclose any information on the biodegradability of such polymers; the only disclosed use is as a plasticizer in PVC polymers. The graft polymers of the type shown in the present invention are neither disclosed nor implied in the prior art.
[0018] WO2022 / 136409 of BASF discloses amphiphilic alkoxylated polyalkyleneimines or amines; no graft polymers are disclosed that have a polymer made from lactone and alkylene oxide as the graft backbone and graft ethylenically unsaturated monomers containing at least one vinyl ester by free radical polymerization. Therefore, except for the following two points, this patent publication is completely irrelevant to the present invention: First, it also relates to polymer structures in a similar technical field to the present invention; Second, the products contain lactone and alkylene oxide. The lactone and alkylene oxide are polymerized to produce lactone-alkylene oxide copolymers, which are then attached to the amino groups of the starting compound polyethylenimine or polyamine. No graft polymerization is carried out after the formation of these side chains. Therefore, such compounds are essentially different from the present invention in terms of structure, preparation process, properties, and thus application functions. The graft polymers of the type shown in the present invention are neither disclosed nor implied in the prior art.
[0019] The cleaning composition disclosed in US2022 / 0056380 has a specific enzyme as the core component, so it neither particularly focuses on a specific polymer itself nor involves its structure, preparation process or characteristics. Among the numerous components of such compositions, graft polymers are only mentioned as general components. However, graft polymers are conventionally known graft polymers (such as the preferably mentioned "BASF HP22"), and the main chains of such polymers do not contain lactones, so such main chains are only composed of alkylene oxides. These alkylene oxides (especially the preferred polymers with a main chain molecular weight of about 6000 g / mol) have almost no biodegradability, and as shown in the present invention, the graft polymers prepared with such polyalkylene oxide main chains have even worse biodegradability. The graft polymers of the type shown in the present invention are neither disclosed nor implied in the prior art.
[0020] Regarding the technical problem of improving the biodegradability of graft polymers based on main chains with polyalkylene oxide units, it has been solved in the unpublished patent application PCT / EP2022 / 065983 (now published as WO2022 / 263354). This patent discloses graft polymers based on main chains containing ester functional groups and polyalkylene oxide units as functional units. The preparation method of the main chain is: oxidizing the polyalkylene oxide in the initial reaction, and then esterifying the oxidized PEG mixture - either by self-esterification or by esterification with an additional polyalkylene oxide. Then the main chain is grafted with vinyl acetate. The polymers in this disclosure have the defect that the synthesis of the main chain requires two-step reactions: first, the oxidation process as the initial reaction step is costly and time-consuming; second, the composition obtained by oxidation is difficult to control because changes in the reaction time will cause changes in the mixture composition. Usually, the resulting mixture contains unoxidized starting materials, polyalkylene oxides with single-terminal hydroxyl groups oxidized to carboxyl functional groups, and polyalkylene oxides oxidized at both ends. Therefore, the flexibility in designing the backbone is highly restricted. This patent application also does not disclose the technical solution of preparing graft polymers using nitrogen-containing monomers.
[0021] Prior Art on the Main Chain
[0022] The present invention discloses the use of three main types of polymer main chains, which contain (oligo / poly) alkylene oxide moieties and (oligo / poly) lactone / hydroxy acid-derived moieties.
[0023] Such main chains are named (A1), (A2), (A3) and (A4) (definitions are given below), and are in principle prior art known:
[0024] (A1)
[0025] WO2002046268 (Cognis, now part of BASF) discloses biodegradable polymers as surfactants, emulsifiers, etc., obtained by reacting an organic initiator with: 1. an alkylene oxide, 2. a mixture of an alkylene oxide and a lactone. The "organic initiator" is defined on page 4 as a mono-functional or multi-functional alcohol or amine.
[0026] To obtain a copolymer from an alkylene oxide and caprolactone, a suitable starting material is reacted with a premixed combination of an alkylene oxide and caprolactone.
[0027] To obtain a main-chain copolymer of type (A1) from an alkylene oxide and a lactone (such as caprolactone), a suitable starting material is reacted with a premixed combination of an alkylene oxide and caprolactone.
[0028] Alcohols containing 2 hydroxyl groups (diols) are used as starting materials. Examples of such diols are: ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, block copolymers of ethylene oxide and propylene oxide, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, etc.
[0029] The alkylene oxides used in combination with caprolactone are: ethylene oxide, 1,2-propylene oxide or 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentylene oxide, preferably ethylene oxide and propylene oxide.
[0030] The copolymerization reaction of an alkylene oxide and caprolactone is carried out under typical conditions of alkoxylation reaction. Basic catalysts such as potassium hydroxide, sodium hydroxide, sodium methoxide, potassium methoxide are used.
[0031] (A2)
[0032] The main-chain polymer of type (A2) can in principle be obtained by the alkoxylation reaction of a poly-lactone.
[0033] The poly-lactone can be obtained, for example, by polymerizing a lactone (such as caprolactone) onto a starting material having 2 hydroxyl groups, such as a diol, such as ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, block copolymers of ethylene oxide and propylene oxide, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, etc.
[0034] The polymerization reaction of caprolactone is carried out in the presence of various catalysts, such as the transesterification catalyst tin(II) alkanoate.
[0035] The alkoxylation reaction of such polycaprolactone is carried out under typical alkoxylation conditions. Since alkoxylation needs to be carried out under basic reaction conditions, transesterification may occur at the ester bond in the polycaprolactone.
[0036] US4281172 describes acrylates from polyester-polyether copolymers. To obtain these structures, polycaprolactone esters derived from monoalcohols, diols, triols or tetraols are reacted with alkylene oxides.
[0037] The polycaprolactone esters are synthesized according to US3169945 by reacting a hydroxyl group-containing component with various catalysts including Ti or Sn catalysts, or alkali metal hydroxides.
[0038] The alkoxylation reaction is catalyzed by BF3-etherate or potassium hydroxide, etc.
[0039] JP07149883 describes a method for obtaining polyester polyols by first reacting a compound containing at least two active hydrogen atoms with a lactone and then reacting with an alkylene oxide. Both reactions are carried out with the same catalyst. The catalyst is an alkali metal hydroxide or an alkali metal alcoholate.
[0040] WO9636656 claims a biodegradable alkylene oxide-lactone copolymer. The polymer is synthesized by first copolymerizing a bifunctional or polyfunctional starter with an alkylene oxide and a lactone, and then end-capping with an alkylene oxide block. The catalyst is an alkali metal hydroxide or an alkaline earth metal hydroxide or a Lewis acid. This patent application describes that the claimed polymer has better biodegradability compared to polyalkylene oxides and is used as a surfactant, emulsifier, etc., but cannot be used as the main chain of a graft polymer.
[0041] (A3)
[0042] (A3)-type main-chain polymers can in principle be obtained by the polycondensation reaction of polyalkylene glycols with lactones, which produces (in short) triblock polymers.
[0043] Using caprolactone and alkylene oxide as raw materials, the synthesis method of a triblock copolymer with an intermediate polyalkylene oxide block includes: 1. reacting a diol or water with an alkylene oxide to form a polyalkoxylate; and 2. polymerizing and grafting caprolactone onto the polyalkoxylate.
[0044] These two reactions can be carried out respectively under the typical reaction conditions of the alkoxylation reaction (producing polyalkoxylate) and the typical reaction conditions of caprolactone polymerization (producing polycaprolactone blocks).
[0045] Such triblock copolymers with a middle polyethylene oxide block have been known since the 1990s. These polymers are used for drug release and solubilization purposes (Z. Zhu et al., Journal of Polymer Science, Part A: Polymer Chemistry 1997, 35(4), 709-714; M. Boffito et al., Journal of Biomedical Materials Research, Part A, 2015, 103A(3), 1276-1290).
[0046] (A4)
[0047] (A4)-type main chains are also known:
[0048] WO96 / 36656 discloses biodegradable alkylene oxide-lactone copolymers and copolyesters, which have been described above for (A3).
[0049] WO2002046268 (Cognis, now part of BASF) discloses alkylene oxide-lactone copolymers, which have been described for (A1).
[0050] However, there is currently no knowledge of a way to use such polymers as the backbone of a graft polymer, i.e., to introduce enhanced biodegradability properties into such graft polymers via this backbone.
[0051] Object of the Invention
[0052] It has been recognized that graft polymers based on conventional polyalkylene oxides (main chains without ester groups) exhibit unexpectedly low percentages of biodegradation, which are often much lower than the expected values calculated from the biodegradation data of pure polyalkylene oxides.
[0053] As the degree of modification of polyalkylene oxides by grafting polymerizable monomers onto such a main chain via free radicals (usually using polyalkylene oxides with two hydroxy end groups, and thus such polyalkylene oxides with hydroxy groups are commonly referred to as "polyalkylene glycols") increases (i.e., the number of side chains on the main chain increases), graft polymers based on such conventional polyalkylene oxides generally exhibit reduced biodegradation performance compared to unmodified polyalkylene oxides and unmodified polyalkylene glycols. This phenomenon is sometimes attributed to a blocking effect on the biodegradation mechanism, since the degradation process of polyalkylene oxide / diol seems to start at its corresponding end groups and then proceeds step by step along the polymer chain. Thus, any additional branched structures on the main chain carbon atoms (which are formed when polymer side chains are grafted onto such a main chain) will impede, and may even completely terminate, the degradation process. It can be inferred therefrom that the higher the grafting degree (i.e., the more side chains attached to the main chain), the lower the percentage of biodegradation of such a graft polymer. Unfortunately, it is also often observed that the higher the degree of branching, the more excellent the performance of the material in the desired application, because only when the number of side chains is high enough will the chemical structure of the main chain be sufficiently changed so that the new graft polymer exhibits specific properties different from a simple mixture of the unmodified main chain and the (unattached / ungrafted) homopolymer that will form the side chains of the graft polymer.
[0054] Therefore, when using polyalkylene oxides as the main chain, the technical problem of how to balance the contradictory characteristics of "a suitable graft polymer with excellent application performance" and "maintaining the percentage of biodegradation of the unmodified main chain (i.e., unmodified polyalkylene oxide / diol)" has not been solved yet.
[0055] Although the unpublished patent application PCT / EP2022 / 065983 first solved the problem of the lack of biodegradation performance of the polyalkylene oxide main chain, it was found that the actual application effect of this solution was still not satisfactory, mainly because: the two-step reaction process was long and costly, requiring two completely different types of chemical reactions (oxidation and polymerization), and the structure regulation was difficult because the oxidation process produced a mixture of compounds such as diols (i.e., the starting material polyalkylene glycol), monoalcohol monocarbonic acids (i.e., partially oxidized polyalkylene glycols), and dicarboxyl polyalkylene oxides (i.e., fully oxidized polyalkylene glycols). The specific structure adopted herein cannot be obtained by the method disclosed in this patent document. Similarly, nitrogen-containing monomers were not disclosed.
[0056] Therefore, it is necessary to improve the biodegradation performance of conventional graft polymers based on polyalkylene oxides by enhancing the biodegradation ability of the grafting substrate and maintaining the overall structure of the graft polymer, so as to maintain or even enhance its application performance; it is also necessary to optimize the cost and efficiency of the unpublished patent application PCT / EP2022 / 065983 by simplifying the production process to only one-step reaction (using only one type of reaction) while improving the controllability of the chemical structure.
[0057] Although (A1), (A2), and (A3) type polymers as defined herein are known, using such polymers as the main chain to prepare graft polymers has not been reported.
[0058] Accordingly, an object of the present invention is to provide novel graft polymers based on a polyalkylene oxide type graft main chain having an ester functional group imparting ability.
[0059] Furthermore, when used in compositions such as cleaning compositions, these novel graft polymers should have beneficial properties regarding biodegradability and / or their washing behavior. Summary of the Invention

Detailed Description of the Invention
[0113] The fabric and home care composition comprises:
[0114] (i) A graft polymer; and
[0115] (ii) One or more fabric and home care ingredients.
[0116] Graft Polymer
[0117] The graft polymer of the present invention comprises a polymer main chain (first structural unit) as a graft substrate and a polymer side chain as a second structural unit.
[0118] First Structural Unit (Main Chain)
[0119] The first structural unit of the graft polymer is a polymer main chain that serves as the graft substrate of the graft polymer of the present invention, wherein the polymer main chain (A) can be obtained by the polymerization reaction of at least one subunit (a1) and at least one subunit (a2).
[0120] The subunit (a1) is made of: at least one alkylene oxide monomer and / or at least one polyalkylene oxide polymer having two hydroxyl end groups, and the alkylene oxide monomer is selected from C₂ to C 10A group of alkylene oxides, preferably C2 to C5 alkylene oxides such as ethylene oxide, 1,2-epoxypropane, 1,2-epoxybutane, 2,3-epoxybutane, 1,2-epoxypentane or 2,3-epoxypentane; 1,4-diols, or their cyclic or oligomeric analogs, or polyether polymers based on such 1,4-diols; 1,6-diols, or their cyclic or oligomeric analogs, or polyether polymers based on such 1,6-diols; or any mixture of any of the above in any proportion, presented as blocks of specific polymer units, statistical polymer structures, or polymers containing one or more homopolymer blocks of specific monomers and one or more statistical blocks containing more than one such monomer, and any combination thereof, such as polymers with several different blocks of two or more different monomers, polymers with blocks of two or more different monomers, or polymers with statistical mixture blocks of two or more monomers, etc.
[0121] As used herein, the term "block (co)polymer" means that the corresponding polymer contains at least two (i.e., two, three, four, five or more) homopolymer or copolymer subunits ("blocks") connected by covalent bonds. A "diblock" copolymer has two independent blocks (homopolymer and / or copolymer subunits), while a "triblock" copolymer has three independent blocks (homopolymer and / or copolymer subunits), and so on. The number of independent blocks in such block copolymers is not limited; accordingly, an "n-block copolymer" contains n independent blocks (homopolymer and / or copolymer subunits). Within each block, the size / length of such block can vary independently of other blocks. The minimum block length / size is based on two individual monomers (as a minimum), but can be as large as 50, even 100 or 200, and any value between 2 and 200. The corresponding monomers used to prepare each block of the block copolymer backbone (a1) can be added sequentially. However, during the feed switch from one monomer to another, there may also be a transition phenomenon, resulting in a so-called "dirty structure", where at the edge / junction of the corresponding block, a small amount of monomers of the corresponding adjacent block may be contained within the individual block under consideration (the so-called "dirty structure" or "dirty channel"). However, preferably, the block copolymer subunits (a1) according to the present invention do not contain any dirty structures at the corresponding junctions of the blocks, but for commercial reasons (i.e., mainly factors such as the cost of efficient reactor utilization), although there may still be a small amount of dirty structures, these are not deliberately introduced products.
[0122] Preferably, at least one monomer in the polymer is derived from the use of ethylene oxide.
[0123] In another embodiment, the structure of the polymer subunit (A1) contains more than one alkylene oxide monomer; in this case, the polymer backbone is a random copolymer, a block copolymer, or a copolymer of a mixed structure comprising: block units (where each block is itself a homopolymer block or a random block), and a statistical / random portion consisting of two or more alkylene oxides, wherein at least one monomer is ethylene oxide. Preferably, the other monomers in addition to ethylene oxide are propylene oxide (PO) and / or 1,2-epoxybutane (BO), and preferably only 1,2-propylene oxide is used.
[0124] The subunit (a2) is made from at least one lactone and / or at least one hydroxy acid.
[0125] At least one lactone and / or hydroxy acid is selected from group i) and / or group ii), where
[0126] i) Lactones, i.e., cyclic esters, starting from α-lactones (three ring atoms), followed by β-lactones (four ring atoms), γ-lactones (five ring atoms), and so on; such lactones are preferably β-propiolactone, γ-butyrolactone, δ-valerolactone, γ-valerolactone, ε-caprolactone, δ-decalactone, γ-decalactone, ε-decalactone; preferably caprolactone;
[0127] and
[0128] ii) Hydroxy acids, which can be derived by hydrolysis from any lactone, particularly from any lactone within group i) above, specifically α-hydroxy acids, β-hydroxy acids or γ-hydroxy acids derived by hydrolysis from the corresponding lactone, as well as lactic acid, glycolic acid, 4-hydroxybutyric acid, 6-hydroxyhexanoic acid, 12-hydroxystearic acid, citric acid; preferably lactic acid or caprolactone, more preferably caprolactone.
[0129] The subunits (a1) and (a2) can be combined in any order according to the application mode of the starting materials and their relative amounts. Thus, by selecting the desired subunits (a1) and (a2), specifically, for subunit (a1), by selecting the number of different alkylene oxides, their relative amounts, their reaction order, etc.; and of course also applicable to subunit (a2), by selecting specific compounds and their relative amounts, etc., the polymer backbone (A) obtained from the reaction of (a1) and (a2) can be defined within a very wide range, specifically achievable in the following three ways:
[0130] -1) First obtain a structurally defined subunit (a1), and then react it with subunit (a2),
[0131] -2) React the alkylene oxide in monomer form from subunit (a1) directly with subunit (a2) in monomer form; or
[0132] -3) Combine the above methods 1) and 2).
[0133] Therefore, three of the most important main chain structures can be defined and obtained:
[0134] (A1):
[0135] The subunit (a2) can be added during the polymerization of the alkylene oxide (a1 unit) to form a random copolymer; in its variant method, a polyalkylene oxide having two hydroxyl groups can be added to this polymerization reaction to introduce a specific (a1) subunit block; this variant method has practical value when any of the following occurs: at least a part of the alkylene oxide used is different from the alkylene oxide used in the preparation of the polyalkylene oxide used simultaneously, or the structure of the polyalkylene oxide (i.e., the arrangement order of the alkylene oxide units) is different from the structure obtained by reacting at least one alkylene oxide used in the copolymerization reaction with the (a2) subunit and the polyalkylene oxide.
[0136] In a simplified method, the (A1) main chain can be described as a structure composed of (a1) subunits and (a2) subunits in a random arrangement order. According to the relative amounts and reactivities of (a1) and (a2), the block lengths of (a1) and (a2) change.
[0137] The following structures can be obtained by this method:
[0138] Poly[random-{lactone}-{alkylene oxide}]
[0139] Therefore, in a preferred embodiment, the polymer main chain is selected from
[0140] (A1) A main chain composed of monomeric, oligomeric, and / or polymeric (a1) subunits and monomeric, oligomeric, and / or polymeric (a2) subunits in a random arrangement order, where there are more than one subunit (a1) and / or more than one subunit (a2).
[0141] (A2):
[0142] The subunit (a2) can first be oligomerized / polymerized and then copolymerized with at least one alkylene oxide to form a mixed random / block structure; according to the degree of oligomerization of the lactone / hydroxy acid and whether there is still lactone / hydroxy acid in monomer form when the alkylene oxide is added, the structure can be further adjusted by adjusting the number and length of the (a2) subunit chains in the (A2) main chain.
[0143] Similar to (A1), in another variant method, a polyalkylene oxide having two hydroxyl groups can also be added to such a polymerization reaction, thereby also introducing a specific (a1) subunit block; this variant method has practical value when any of the following situations occur: at least a part of the alkylene oxide used is different from the alkylene oxide used in the preparation of the polyalkylene oxide used simultaneously, or the structure of the polyalkylene oxide (i.e., the arrangement order of the alkylene oxide units) is different from the structure obtained by reacting at least one alkylene oxide used in the copolymerization reaction with the (a2) subunit and the polyalkylene oxide.
[0144] In a simplified method, the (A2) main chain can be described as a triblock polymer having an internal (a2) block and two external (a1) blocks. (Reversing the order generates structure (A3); see below.)
[0145] The following structure (in its simplest form) can be obtained by this method:
[0146] [PAG]-[oligomeric / polymeric lactone]-[PAG]
[0147] ("Lactone" used here refers to the (a2) subunit and is thus made from lactone / hydroxy acid, which can be either a single monomer unit or an oligomeric or polymeric unit made from monomers through an initial reaction step; "PAG" (i.e., polyalkylene glycol) here is used to represent the (a1) subunit)
[0148] In the case where the starting material of the (a2) subunit has not completely reacted, the structure will no longer be a true triblock structure but will additionally contain more shorter (a2) units in the chain, thus forming a multiblock structure and even turning into a mixture of block and random arrangement structures.
[0149] Therefore, in a preferred embodiment, the polymer main chain is selected from the (A2) main chain composed of an oligomeric or polymeric subunit (a2) as an internal block and two oligomeric and / or polymeric (a1) subunit external blocks, defined as "-[(a1) block]-[(a2) block]-[(a1) block]-", and may also include higher-order block polymers such as pentablock, heptablock, nonablock, etc., where (a1) and (a2) blocks are further connected outside the triblock structure, such as the pentablock structure "[(a1) block]-[(a2) block]-[(a1) block]-[(a2) block]-[(a1) block]-[(a2) block]-[(a1) block]" etc.
[0150] (A3):
[0151] The subunit (a2) can be added after the alkylene oxide oligomerization reaction or after the (near-complete) polymerization reaction, thereby generating a block structure containing longer (a2) chains and longer (a1) chains; in the case where the complete polymerization of (a1) is completed before adding (a2), the resulting structure can be described as "(a2)-polyalkylene oxide-(a2)"; such a structure can also be obtained by the direct reaction of polyalkylene oxide with (a2). More complex structures can be obtained by the following two methods: first, only the alkylene oxide is oligomerized, and then the mixture containing the alkylene oxide oligomer and the monomeric alkylene oxide is reacted with (a2); or (a2) is polymerized with the alkylene oxide and the polyalkylene oxide.
[0152] In a simplified method, the (A3) main chain can be described as a triblock polymer having an internal (a1) block and two external (a2) blocks:
[0153] (Reversing the order generates the structure (A2); see above.)
[0154] [Oligo / polyester]-[PAG]-[Oligo / polyester]
[0155] ("Oligo / polyester" represents the (a2) subunit and is thus made from lactone / hydroxy acid; here "PAG" (i.e., polyalkylene glycol) is used to represent the (a1) subunit)
[0156] Thus, in a preferred embodiment, the polymer main chain is selected from the (A3) main chain consisting of an internal block of oligomeric and / or polymeric (a1) subunits and two external blocks of oligomeric or polymeric subunits (a2), in the form of at least a triblock polymer, defined as "-[(a2) block]-[(a1) block]-[(a2) block]-".
[0157] Similar to the case of (A2), in the case where the starting material of the (a2) subunit has not completely reacted, the structure will no longer be a true triblock structure, but will additionally contain more shorter (a1) units in the chain, thus forming a multi-block structure and even turning into a mixture of block and random arrangements.
[0158] Similarities of (A1), (A2), and (A3)
[0159] When adding the corresponding other subunit substances, the more unreacted (a2) substances (in the case of the (A2) main chain) or the more unreacted (a1) substances (in the case of the (A3) main chain), the smaller the difference between (A2) and (A3).
[0160] In the extreme case, the result of this operation will be the complete copolymerization reaction of the subunits (a1) and (a2), and thus its structure will also be similar to or even identical to (A1).
[0161] Thus, (A1), (A2), and (A3) are merely extreme examples in the general principle of copolymerizing alkylene oxides, polyalkylene glycols, and lactones / hydroxy acids in every conceivable order of arrangement, proportion, and variation of reaction time before adding other starting materials.
[0162] Thus, in a preferred embodiment, the polymer backbone is selected from backbones obtained according to the following general principle: alkylene oxides, polyalkylene glycols, and lactones / hydroxy acids are copolymerized in every conceivable order of arrangement, proportion, and variation of reaction time before adding other starting materials.
[0163] In a preferred embodiment, the polymer backbone serving as the graft substrate contains at least one subunit (a1) and at least one subunit (a2), wherein
[0164] (a1) is a unit containing, preferably consisting essentially of, a moiety derived from at least one alkylene oxide monomer and / or at least one polyalkylene oxide polymer having two hydroxyl end groups, and the alkylene oxide monomer is selected from C2 to C 10 alkylene oxides, preferably the group of C2 to C5 alkylene oxides,
[0165] (a2) is a unit containing, preferably consisting of, at least one lactone and / or at least one hydroxy acid, and such a subunit (a2) is a moiety derived from a single lactone and / or hydroxy acid or an oligomeric or polymeric unit composed of at least one type of lactone and / or at least one type of hydroxy acid,
[0166] wherein preferably, the at least one lactone and / or hydroxy acid is selected from group i) and / or group ii), wherein
[0167] i) lactones, i.e., cyclic esters, starting from α-lactones (three ring atoms), followed by β-lactones (four ring atoms), γ-lactones (five ring atoms), and so on; such lactones are preferably β-propiolactone, γ-butyrolactone, δ-valerolactone, γ-valerolactone, ε-caprolactone, δ-decalactone, γ-decalactone, ε-decalactone; preferably caprolactone; and
[0168] ii) hydroxy acids, which can be derived by hydrolysis from any lactone, particularly from any lactone within group i) above, specifically α-hydroxy acids, β-hydroxy acids, or γ-hydroxy acids derived by hydrolysis from the corresponding lactones, as well as lactic acid, glycolic acid, 4-hydroxybutyric acid, 6-hydroxyhexanoic acid, 12-hydroxystearic acid, citric acid; preferably lactic acid or caprolactone, more preferably caprolactone, and the polymer backbone is obtained by the following:
[0169] (A1) copolymerize at least one subunit (a1) with at least one subunit (a2), wherein in this copolymerization of at least one subunit (a1) and at least one subunit (a2), optionally at least one oligomer or polymer prepared from at least one subunit (a1) or at least one subunit (a2) can also be used;
[0170] (A2) First carry out oligomerization / polymerization on subunit (a2), and then carry out polymerization on the product with subunit (a1); or
[0171] (A3) First carry out oligomerization / polymerization on subunit (a1), and then carry out copolymerization on the product with subunit (a2);
[0172] (A4) First provide a side-capped oligomeric or polymeric subunit (a1), which is preferably etherified with an alcohol, more preferably etherified with a C1 to C4 short-chain alcohol. This subunit then reacts as a starting block with at least one subunit (a2) and / or at least one subunit (a1), where the subunit (a1) can be different from the subunit (a1) in the starting block or can be arranged in a different order compared to the subunit (a1) in the starting block, to attach a new block containing a portion of the subunits used in the (co)polymerization reaction to the uncapped side of the starting block, thereby obtaining a diblock structure, i.e., [capping group]-[subunit (a1)]-[subunit (a2)] or [capping group]-[subunit (a1)]-[random-{subunit (a2)-subunit (a1)}];
[0173] where in the case where there are already more than one subunit (a1) and / or more than one subunit (a2) present in the oligomer or polymer used, these subunits can be arranged in any order within such used oligomer or polymer, and
[0174] where in the presence of more than one subunit (a1) and / or more than one subunit (a2)
[0175] for the case of this polymerization reaction, these subunits (and the optional oligomer / polymer if used) can be arranged in any order within the obtained main chain;
[0176] and where - optionally - the main chain structure contains at least one starting molecule.
[0177] The polymer main chain (A), especially (A1), (A2), and (A3), can optionally be capped at the end groups, and this capping treatment uses known techniques, through C1 to C 25The capping is carried out with an alkyl group (preferably a C1 to C4 group). This capping treatment will be carried out after the preparation of the main chain and preferably can be completed before grafting.
[0178] In the case of (A4), a capping treatment of one end group needs to be carried out before the polycondensation reaction with subunit (a1) and / or subunit (a2), because only in this way can the (A4) structure be obtained subsequently. In another more preferred method, the preparation of (A4) starts from a monoalcohol, and then it is reacted with an alkylene oxide to obtain a "mono-end-capped" oligomer / polymer of subunit (a1) (the end of the oligo / polyalkylene oxide chain carries a hydroxyl group), and then it is reacted with subunit (a2) to obtain the (A4) structure.
[0179] When preparing oligo / polyalkylene oxide as the starting block, a diol can be used as the starting molecule to prepare the oligo / polyalkylene oxide. Therefore, such an oligo / polymer of subunit (a1) can contain a part derived from such a diol in its structure. Diols for such uses and methods for preparing such oligo / polyalkylene oxides containing diols in their structure are known. Typical diols include ethylene glycol, propylene glycol, etc. In principle, all known diols can be used for this purpose.
[0180] In another preferred embodiment, the polymer main chain as the grafting substrate contains at least one subunit (a1) and at least one subunit (a2), where
[0181] (a1) is a unit containing the following part, preferably consisting essentially of the following part: a part derived from at least one alkylene oxide monomer and / or at least one polyalkylene oxide polymer having two hydroxyl end groups, and the alkylene oxide monomer is selected from C2 to C 10 alkylene oxide, preferably the C2 to C5 alkylene oxide group,
[0182] (a2) is a unit containing the following part, preferably consisting of the following part: at least one lactone and / or at least one hydroxy acid. Such a subunit (a2) is a part derived from a single lactone and / or hydroxy acid, or an oligomeric or polymeric unit composed of at least one type of lactone and / or at least one type of hydroxy acid,
[0183] where preferably, the at least one lactone and / or hydroxy acid is selected from group i) and / or group ii), where
[0184] i) Lactones, that is, cyclic esters, starting from α-lactones (three ring atoms), followed by β-lactones (four ring atoms), γ-lactones (five ring atoms), and so on; such lactones are preferably β-propiolactone, g-butyrolactone, δ-valerolactone, g-valerolactone, e-caprolactone, d-decalactone, g-decalactone, e-decalactone; preferably caprolactone; and
[0185] ii) Hydroxy acids, which can be derived by hydrolysis from any lactone, particularly from any lactone within group i) above, specifically α-hydroxy acids, β-hydroxy acids or γ-hydroxy acids derived by hydrolysis from the corresponding lactone, as well as lactic acid, glycolic acid, 4-hydroxybutyric acid, 6-hydroxyhexanoic acid, 12-hydroxystearic acid, citric acid;
[0186] Preferably lactic acid or caprolactone, more preferably caprolactone,
[0187] wherein the polymer backbone serves as the grafting substrate (A),
[0188] wherein the polymer backbone is selected from
[0189] (A1) A backbone composed of monomeric, oligomeric and / or polymeric (a1) subunits and monomeric, oligomeric and / or polymeric (a2) subunits in a random arrangement order, where there is more than one subunit (a1) and / or more than one subunit (a2);

[0191] (A3) A backbone composed of oligomeric and / or polymeric (a1) subunit inner block and two oligomeric or polymeric subunit (a2) outer blocks, in the form of at least a triblock polymer, defined as "-[(a2) block]-[(a1) block]-[(a2) block]-",

[0195] (ii) having oligomeric or polymeric subunit (a1); and

[0197] This diblock structure has the following idealized structure when only using subunit (a2): [capping group]-[subunit (a1)]-[subunit (a2)]
[0198] Or when using subunits (a1) and (a2):
[0199] [capping group]-[subunit (a1)]-[random-{subunit (a2)-subunit (a1)}];
[0200] And wherein - optionally - at least one starting molecule is included in this main chain structure.

[0247] In an even more preferred embodiment of the previous embodiment, substantially no other monomer (B3) is used.
[0248] In an even more preferred embodiment of the previous embodiment, substantially no other monomer (B2) or (B3) is used.
[0249] In a preferred embodiment, the graft polymer of the present invention consists of monomers, wherein

[0253] wherein the vinyl ester monomer (B1) is optionally partially or completely hydrolyzed after the polymerization reaction.
[0254] In its preferred embodiment, the vinyl ester is not hydrolyzed.
[0255] In an alternative embodiment, in addition to at least one monomer (B1), vinyl pyrrolidone is present as monomer (B2), wherein monomer (B1) preferably comprises vinyl acetate, and even more preferably is only vinyl acetate. Even more preferably, vinyl acetate is the only monomer (B1), and vinyl pyrrolidone is the only monomer (B2).
[0256] In an alternative embodiment to the embodiment described in the immediately preceding paragraph, monomer (B1) can be partially or completely hydrolyzed after the polymerization reaction. In a preferred embodiment thereof, monomer (B1) is partially hydrolyzed, and the degree of hydrolysis is even more preferably at most 80 mol%, 70 mol%, 60 mol%, 50 mol%, 40 mol%, 30 mol%, 20 mol% or 10 mol% based on the total amount of monomer (B1).
[0257] Preferably, monomer (B1) is partially hydrolyzed, and the degree of hydrolysis is at least 20% and at most 50%. In a most preferred embodiment among the foregoing embodiments, vinyl acetate is used as monomer (B1), vinyl pyrrolidone is used as monomer (B2), and the polymer portion derived from vinyl acetate is partially hydrolyzed after the polymerization reaction. The amount of hydrolysis is preferably about 20 mol% to 50 mol%, more preferably about 30 mol% to 45 mol%, such as about 40 mol% based on the total amount of vinyl acetate.
[0258] In an alternative and even more preferred embodiment to the embodiments described in the immediately preceding two paragraphs, the vinyl ester is not hydrolyzed at all.
[0259] It should be understood that the amounts of (A), (B), (B1), (B2), (B3) and other monomers other than the foregoing monomers can each independently be selected from the various ranges given in detail, that is: the upper and lower limits can also form a numerical range not explicitly indicated by combining two different ranges given for a certain element (such as such a combined range for (A), (B), (B1), (B2) and (B3)), but the present invention clearly aims to cover such combined ranges.
[0260] In addition, in an embodiment of the present invention, a wide range and a very particularly preferred narrow range can be used in combination, where the range selection of one component is independent of the range selection of the other component, provided that the total amount of each component constitutes "100% polymer": for example, the most preferred ranges of (A) and (B) can be selected and combined with the widest possible range given for (B1) / (B2) / (B3), and any other possible combinations are covered.
[0261] Preferably, the same selection criteria should be adopted for all possible selections of (A) / (B) and (B1) / (B2) / (B3), for example, all select the "preferred" range, or more preferably all select the "more preferred" range, or most preferably all select the "most preferred" range.
[0262] The polydispersity (PDI) Mw / Mn of the graft polymer of the present invention as described in detail above is at most 10, preferably at most 5, more preferably at most 3, and most preferably in the range of 1.0 to 2.6; and is any value a as an upper or lower limit, and any range in between (such as 1.3 to 2.6, 1 to 3, etc.) (where Mw = weight average molecular weight, unit g / mol; Mn = number average molecular weight, unit g / mol; where PDI is a dimensionless quantity), the lower the value, the more preferred, but specifically depends on the Mn of the polymer backbone used ((A) the higher the Mn, the higher the PDI usually) and the amount of (B) ((B) the higher the amount relative to (A), the higher the PDI usually).
[0263] M w and M n The corresponding values of and can be determined using GPC standard methods (such as the methods mentioned in the experimental section). However, the molecular weights of the main chains used in the present invention can also be calculated because these reactions are basically complete. Therefore, it is also a feasible method to calculate the molecular weight based on the total molar amount of the components used in the preparation reaction. The graft polymer of the present invention may contain a certain amount of ungrafted polymer ("ungrafted side chain") made from monomers that did not react with the polymer backbone (i.e., were not grafted to the polymer backbone, or were not grafted onto the polymer backbone).
[0264] The content of such ungrafted polymer may be higher or lower (depending on the reaction conditions), but preferably the content is reduced, and thus a lower content is more preferred. By this reduction, the amount of grafted side chains is preferably increased. This reduction in content can be achieved by appropriate reaction conditions, such as controlling the feed amounts of the monomer and the free radical initiator and their relative amounts, as well as the ratio relationship with the amount of the main chain. This adjustment is generally known to those skilled in the art and will be elaborated in detail in the process description of obtaining the graft polymer of the present invention below.
[0265] It has been found that the graft polymer of the present invention as described in detail above shows an improved biodegradability of at least 35%, more preferably at least 40%, even more preferably at least 50%, such as 41%, 42%, 43%, 44%, 45%, etc., 51%, 52%, 53%, etc., 55%, 60%, 65%, etc., and any value between the above values and up to 100% within 28 days when tested according to OECD 301F.

[0267] (A) 20% to 95%, preferably 30% to 90%, more preferably 40% to 85%, most preferably 50% to 80% of the polymer backbone, which serves as the grafting substrate, and

[0344] In addition, the graft polymer solution preferably has a suitable viscosity, which should be within a suitable range when at a reasonably high polymer solid concentration (to meet the processing requirements during and after production and to be provided in the form required by the user, for example, as a "pure" (usually liquid at this time) product, dissolved in a solvent (typically an aqueous solution (containing water and an organic solvent), water only, or an organic solvent only)), to allow typical technical process steps such as pouring, pumping, metering, etc. Therefore, the viscosity should preferably be in the range of at most about 4000 mPas, more preferably at most 3500 mPas, even more preferably at most 3000 mPas, such as at most 4500 mPas, 3750 mPas, 3250 mPas, 2750 mPas, or even 2600 mPas, or less than, for example, 2500 mPas, 2000 mPas, 1750 mPas, 1500 mPas, 1250 mPas, 1000 mPas, 750 mPas, 500 mPas, 250 mPas, 200 mPas, 150 mPas, or 100 mPas. The concentration of the polymer (defined as the weight percentage of the dry polymer in the total weight of the polymer solution, based on the total solid content of the polymer in the solution) is preferably at least 10 wt%, more preferably at least 20 wt%, and even more preferably at least 40 wt%, and most preferably at least 50 wt%, such as at least 60 wt%, 70 wt%, 80 wt%, or even 90 wt%. The viscosity can be measured at 25 °C or an elevated temperature, such as 50 °C or even 60 °C. Thereby, the polymer solution can be suitably processed on a commercial scale. Of course, it is obvious that depending on the amount of solvent added, when the amount of solvent increases, the viscosity is lower, and vice versa, thus allowing adjustment in the desired situation. It is also obvious that the measured viscosity depends on the temperature at which it is measured. For example, when measured at a lower temperature, the viscosity of a given polymer with a given solid content of, for example, 80 wt% will be higher, while when measured at a higher temperature, the viscosity will be lower. In a preferred embodiment, the solid content is between 70 wt% and 99 wt%, more preferably between 75 wt% and 85 wt%, and no additional solvent is added except for the polymer prepared.In a more preferred embodiment, the solids content is between 70% and 99% by weight, more preferably between 75% and 95% by weight, no additional solvent is added apart from the polymer being prepared, and the viscosity is below 3000 mPas, more preferably 3250 mPas, or even below 2750 mPas, 2600 mPas, 2500 mPas, 2000 mPas, 1750 mPas, 1500 mPas, 1250 mPas, 1000 mPas, 750 mPas, 500 mPas, or even 250 mPas when measured at 60 °C. The viscosity can be determined as is commonly known for such polymers, preferably as described in the experimental section below.
[0345] As a further criterion, of course, the specific properties of the particular polymer need to be evaluated and each specific formulation ranked accordingly in the particular field of application. Due to the wide range of uses of the polymers of the present invention, it is not possible to give an exhaustive overview or detailed guidance for each field of application, but the present specification and examples give guidance on how to prepare and select useful polymers with the desired properties and how to adjust these properties to meet the requirements. One such criterion in the field of home care, in particular in the field of fabric care, is of course its performance during washing, for example subjecting certain materials showing stains of certain materials to a defined washing program.
[0346] The examples provide some guidance for the application of washing fabrics, i.e. the general field of fabric care.
[0347] Depending on the individual need for polymers showing a defined degree of biodegradability, water solubility and viscosity (i.e. handling properties), the general and specific teachings herein (not intended to be limited to the specific examples given) will guide on how to obtain such polymers.

[0350] It must be noted that the "grafting method" in which a polymer backbone (such as the polymer backbone (A) described above) is grafted with polymer side chains is itself known to those skilled in the art.

[0351] Radical polymerization itself is also known to those skilled in the art. Those skilled in the art also know that the method of the present invention can be carried out in the presence of a radical-forming initiator (C) and / or at least one solvent (D).
[0352] Those skilled in the art know the respective components suitable for such uses.
[0353] The term "radical polymerization" used in the context of the present invention includes, in addition to radical polymerization, its variants such as controlled radical polymerization. Suitable control mechanisms are RAFT, NMP or ATRP, each of which is known to those skilled in the art, including suitable control agents.

In a preferred embodiment, monomer (B2) is not used. In a more preferred embodiment, neither monomer (B2) nor monomer (B3) is used. In an even more preferred embodiment, only monomer (B1) is used.

[0356] Generally, apart from monomers (B1), (B2) and (B3), at least one other monomer different from the aforementioned monomers can be used for carrying out the (co)polymerization reaction to produce the side chain (B), where such other monomer is present in an amount of less than 2% in the total amount of monomers used to obtain the polymer side chain (B), and is preferably present only as an impurity which cannot be avoided in practice and not deliberately added for the polymerization reaction, most preferably is completely absent.
[0357] In a more preferred embodiment of the foregoing two paragraphs, with regard to the monomer amounts and ratios, the following additional provisions 1) (the case when (B2) is present) and 2) (the case when (B2) is absent) apply:
[0358] In the case of using monomer (B2), based on the total weight of the graft polymer, the monomer amounts are as follows:

[0362] (B3) (Other monomers) is 0% to 10%, preferably at most 2%, more preferably at most 1%, even more preferably about 0%, but in all cases at most 10% of the amount of (B1), and does not exceed the amount of (B2).
[0363] The amounts of other monomers other than (B1), (B2), and (B3) are as detailed above, and monomers (B1), (B2), and (B3) are those monomers detailed in any of the foregoing disclosed embodiments.
[0364] In the case of not using monomer (B2), based on the total weight of the graft polymer, the monomer amounts are as follows:
[0365] B) is 5% to 60%, preferably at most 50%, and preferably at least 20%;

[0368] (B3) (Other monomers) is from 0% to 10%, preferably at most 2%, more preferably at most 1%, and even more preferably about 0%.
[0369] The amounts of other monomers in addition to (B1), (B2) and (B3) are as detailed above, and the monomers (B1), (B2) and (B3) are those monomers detailed in any of the embodiments disclosed above.
[0370] In a preferred embodiment, the amount of vinyl ester monomer (B1) used is generally not less than 10% by weight (relative to the sum of (B1) and (B2)).
[0371] Preferably, the optional other monomer (B3) is also present only as an impurity and not deliberately added for the polymerization reaction. More preferably, based on the total weight of monomer (B1), this amount is less than 1%, more preferably less than 0.5%, even more preferably less than 0.01%, and most preferably there is substantially no such monomer (B3), and most preferably there is not even any other monomer except monomer (B1) and optional monomer (B2). This also applies to other monomers in addition to (B1), (B2) and (B3).
[0372] In a particularly preferred embodiment, based on the total weight of the graft polymer, the amounts of the monomers used are as follows:
[0373] (A) accounts for 40% to 90% of the polymer backbone as defined above, preferably at least 50%, more preferably at least 60%, and preferably at most 80%, and preferably at least one of (A1), (A2) and (A3) is used as the graft substrate.
[0374] (B) is 10% to 60%, preferably at most 50%, more preferably at most 40%, and preferably at least 20%;
[0375] (B1) Vinyl ester is 9% to 55%, preferably at most 50%, more preferably at most 40%, even more preferably at most 35%, and even more preferably at most 30%;
[0376] (B2) Vinylpyrrolidone is 1% to 25%, preferably at most 20%, more preferably at most 15%, even more preferably at most 10%, such as even only at most 5%, where the amount of (B2) is at most not more than the amount of (B1);
[0377] (B3) (Other monomers) is 0% to 2%, preferably at most 1%, more preferably 0%, but in all cases is at most 10% of the amount of (B1) and does not exceed the amount of (B2);
[0378] More preferably, any optional additional monomer (B3) and any other monomers other than (B1), (B2), and (B3) are preferably present only as impurities and not deliberately added for the polymerization reaction; more preferably, based on the total weight of monomer (B1), the amount is less than 1% by weight, more preferably less than 0.5% by weight, even more preferably less than 0.01% by weight, and most preferably there are substantially no such monomers (B3) nor any other monomers, and most preferably there are no other monomers at all even in addition to monomers (B1) and (B2).
[0379] The amount of vinyl ester monomer (B1) is generally not less than 10% by weight (relative to the sum of (B1) and (B2)).
[0380] In an alternatively particularly preferred embodiment, based on the total weight of the graft polymer, the amounts of the monomers used are as follows:
[0381] (A) accounts for 40% to 90% of the polymer backbone as defined above, preferably at least 50%, more preferably at least 80%, and preferably at least one of (A1), (A2), and (A3) is used as the graft substrate;
[0382] (B) is 10% to 60%, preferably at most 50%, and preferably at least 20%;
[0383] (B1) vinyl ester is the total amount of (B) minus the total amount of (B3);
[0384] (B2) is 0%;
[0385] (B3) (other monomers) is 0% to 2%, preferably at most 1%, more preferably 0%, but in all cases at most 10% of the amount of (B1) and does not exceed the amount of (B2);
[0386] The amount of vinyl ester monomer (B1) is generally not less than 10% by weight (relative to the sum of (B1) and (B2));
[0387] Any optional additional monomer (B3) and any other monomers other than (B1), (B2), and (B3) are preferably present only as impurities and not deliberately added for the polymerization reaction. More preferably, based on the total weight of monomer (B1), the amount is less than 1% by weight, more preferably less than 0.5% by weight, even more preferably less than 0.01% by weight, and most preferably there are substantially no such monomers (B3) nor any other monomers, and most preferably there are no other monomers at all even in addition to monomer (B1).
[0388] In each case based on the polymer side chain (B), the amount of the ((free) radical-forming) initiator (C) is preferably 0.1% to 5% by weight, particularly 0.3% to 3.5% by weight.
[0389] For the process according to the invention, it is preferred that the steady-state concentration of free radicals present at the average polymerization temperature remains substantially constant, and that the graft monomers (B), in particular (B1), more preferably (B1) and (B2), even more preferably (B1), (B2) and (B3), are always present in the reaction mixture only in low concentrations (for example, not more than 5% by total weight). This allows the reaction to be controlled and graft polymers with the desired low polydispersity to be prepared in a controlled manner.
[0390] To ensure safe temperature control (especially when the polymerization is initiated at high solid concentrations or in bulk and / or when a large amount of monomer is present initially), it is recommended and thus preferred to take additional effective temperature control measures. This can be done by external and / or internal cooling; such cooling can be achieved by internal and / or external coolers (such as heat exchangers), or when operating at the boiling point temperature of a solvent or solvent mixture under a given temperature / pressure combination, by using a reflux condenser.
[0391] Of course, the same measures can also be used for the preferred embodiments mentioned above, where the monomers are added continuously over a longer period of time so that the monomer concentration in the reaction system remains low over time.
[0392] However, under such conditions, temperature control is usually not a critical control point, since the temperature is at least partially also controlled by the course of the polymerization reaction achieved by regulating the free radical concentration and the available amount of polymerizable monomers. Of course, depending on the scale of the polymerization reaction, such additional cooling measures as described above may be necessary for both of the following process variants: batch or bulk reactions where a large amount of monomer is present initially, or semi-continuous or continuous polymerization reactions where the monomer concentration is usually continuously low - when the scale of the reaction becomes large enough that the volume-to-surface area ratio of the polymerization mixture increases significantly.
[0393] However, those skilled in the art in the field of commercial-scale polymerization are usually aware of this common technical knowledge and can thus make adaptations to meet the requirements.
[0394] According to the invention, the addition process of the initiator (C) and the graft monomers (B) (in particular (B1) and / or (B2) and / or (B3)) preferably employs a dual "and" connection structure and is achieved in the following advantageous manner: there is a substantially constant low concentration of undecomposed initiator and graft monomers (B) in the reaction mixture, where (B1) in particular remains at a constant low level, while (B2) in particular maintains an even lower concentration. Based on the total amount of initiator metered during monomer addition, the proportion of undecomposed initiator in the overall reaction mixture is preferably ≤ 15% by weight, especially ≤ 10% by weight.
[0395] In a more preferred embodiment, the method comprises polymerizing at least one vinyl ester monomer (B1), optionally at least one nitrogen-containing monomer (B2), optionally at least one other monomer (B3) and optionally at least one other monomer (more preferably only monomers (B1) and (B2)) in the presence of at least one polymer backbone (A) as defined herein (which is preferably selected from (A1), (A2) and (A3)), a radical-forming initiator (C) and, if desired, at least one solvent (D) up to a maximum of 50% by weight based on the sum of components (A), (B) and (C) at an average polymerization temperature at which the decomposition half-life of the initiator (C) is from 40 minutes to 500 minutes, in such a way that the content of unreacted graft monomers (B) and the initiator (C) in the reaction mixture is always substoichiometric with respect to the polymer backbone (A), wherein preferably at least 10% by weight of the total amount of vinyl ester monomer (B1) of vinyl ester monomers are selected from vinyl acetate, vinyl propionate and vinyl laurate, more preferably from vinyl acetate and vinyl laurate, and most preferably vinyl acetate, and wherein the remaining amount of vinyl ester can be any other known vinyl ester, wherein preferably at least 60% by weight, more preferably at least 70% by weight, even more preferably at least 80% by weight, even more preferably at least 90% by weight and most preferably substantially only (i.e. about 100% by weight or even 100% by weight) vinyl acetate is used as the vinyl ester (weight percentages are based on the total weight of the vinyl ester monomer B1 used).
[0396] In an even more preferred embodiment of the foregoing embodiment, monomer (B2) is used substantially not in addition to monomer (B1), and (B1) preferably comprises vinyl acetate, more preferably consists essentially of vinyl acetate, all within the ranges and preferences given in the section "Graft polymers of the invention".
[0397] In an alternative embodiment of the foregoing embodiment, substantially only monomer (B2) is used in addition to monomer (B1), (B1) preferably comprises vinyl acetate, more preferably consists essentially of vinyl acetate, and preferably vinyl pyrrolidone is present as (B2), all within the ranges and preferences given in the section "Graft polymers of the invention".
[0398] The average polymerization temperature of the main polymerization reaction and the post-polymerization reaction is suitably in the range from 50 °C to 140 °C, preferably in the range from 60 °C to 120 °C, and more preferably in the range from 65 °C to 110 °C. Usually, the temperature of the post-polymerization reaction is 5 °C to 40 °C higher than that of the polymerization reaction.
[0399] The term "average polymerization temperature" is hereby intended to mean that, although the process is essentially isothermal, due to the exothermic nature of the reaction, there may be temperature variations which are preferably kept within the range of + / - 10 °C, more preferably within the range of + / - 5 °C.
[0400] According to the invention, the decomposition half-life of the initiator (C) (formation of free radicals) at the average polymerization temperature should be from 40 minutes to 500 minutes, preferably from 50 minutes to 400 minutes, and more preferably from 60 minutes to 300 minutes.

[0433] -aliphatic ketones preferably having 3 to 10 carbon atoms such as acetone, methyl ethyl ketone, diethyl ketone and cyclohexanone;
[0434] -cyclic ethers, especially tetrahydrofuran.
[0435] The solvent (D) is advantageously one of those solvents which are also used for formulating the graft polymers of the invention for use (e.g. in washing and cleaning compositions) and which can thus be retained in the polymerization product.
[0436] Preferred examples of these solvents are polyethylene glycols having 2 to 15 ethylene glycol units, polypropylene glycols having 2 to 6 propylene glycol units, especially the alkoxylation products of C6-C8 alcohols (alkylene glycol monoalkyl ethers and polyalkylene glycol monoalkyl ethers). Particularly preferred here are C8-C 16Alkoxylated alcohols, such substances being capable of formulating a free-flowing polymer mixture at 40 °C to 70 °C, the polymer mixture having a very low polymer content while maintaining a low viscosity. Branching can be present in the alkyl chain of the alcohol and / or in the polyalkoxylate moiety (copolymerization of at least one propylene oxide, butylene oxide or isobutylene oxide unit). Particularly suitable examples of these alkoxylated products are 2-ethylhexanol or 2-propylheptanol alkoxylated with 1 mol to 15 mol of ethylene oxide, C 13 / C 15 oxo alcohols or C 12 / C 14 or C 16 / C 18 fatty alcohols, preferably 2-propylheptanol alkoxylated with 1 mol to 15 mol of ethylene oxide and 1 mol to 3 mol of propylene oxide.
[0437] In an alternative embodiment, the polymerization reaction is carried out using a mixture of at least one organic solvent and water.
[0438] In a preferred embodiment, the amount of water during the polymerization reaction is low, preferably at most 10% by weight, more preferably at most 5% by weight, even more preferably at most 1% by weight, based on the total amount of solvent.
[0439] In another alternative embodiment, water is used as the solvent (D) for the polymerization reaction. However, water as the sole solvent is not preferred.
[0440] The free radical initiator (C) is preferably used in the form of a concentrated solution in one of the aforementioned solvents. The concentration of course depends on the solubility of the free radical initiator. Preferably, the concentration is as high as possible to allow the introduction of as little organic solvent as possible into the polymerization reaction. In the case where the initiator is soluble in water and thus water is used as the solvent for introducing the initiator, the concentration does not need to be strictly controlled from the perspective of the residual amount of water.
[0441] Preferably, based on the total weight of the graft polymer (at the end of the polymerization reaction) or based on the total weight of (A) and (B) (at the start of the polymerization reaction), the amount of water during the polymerization reaction is at most 10% by weight, preferably at most 5% by weight, more preferably at most 1% by weight.
[0442] In the process according to the invention, the polymer backbone (A), the graft monomer (B), the initiator (C) and, if applicable, the solvent (D) are generally heated in a reactor to a selected average polymerization temperature.
[0443] According to the present invention, the polymerization is carried out in such a way that an excess of polymer (polymer backbone (A) and the formed graft polymer) is always present in the reactor. The quantitative ratio of the polymer to the ungrafted monomers and the initiator is generally ≥10:1, preferably ≥15:1, and more preferably ≥20:1.
[0444] The polymerization process according to the present invention can in principle be carried out in various reactor types. Such reactor types are well known in the art and include not only any stirred reactor (such as a reaction kettle), but also tubular reactors, cascade reactors composed of reaction kettles or various tubular devices, etc.
[0445] The reactor used is preferably a stirred tank, in which the polymer backbone (A) (if applicable), together with a part of the graft monomers (B), initiator (C) and solvent (D) usually up to 15% by weight of the specific total amount, is first completely or partially filled and then heated to the polymerization temperature, and the remaining amounts of (B), (C) and (if applicable) (D) are metered in, preferably metered in separately. The remaining amounts of (B), (C) and (if applicable) (D) are preferably metered in over a period of ≥2 h, more preferably ≥4 h and most preferably ≥5 h.
[0446] In the case of a particularly preferred, substantially solvent-free process variant, the entire amount of the polymer backbone (A) is first charged as a melt, and then the graft monomers (B1) and (if applicable) (B2) and / or (B3), and preferably the initiator (C) in the form of a 10% to 50% by weight solution prepared with one of the solvents (D) are metered in, and the temperature is controlled such that the average polymerization temperature selected during the polymerization reaction is maintained within a range of especially + / -10 °C, particularly + / -5 °C.
[0447] In another particularly preferred low-solvent process variant, except that the solvent (D) is metered in during the polymerization process to limit the viscosity of the reaction mixture, the procedure is as described above. It is also possible to start metering the addition of the solvent only during subsequent polymerization, or to add it in batches.
[0448] The polymerization can be carried out at standard pressure or at reduced or elevated pressures. When the boiling points of the monomers (B1) and / or (B2) (if (B3) is used, it also includes the monomer (B3)) and / or any solvent (D) used are exceeded at the selected pressure, the polymerization reaction needs to be carried out under reflux cooling.
[0449] After the main polymerization reaction, a post-polymerization process step can be added. To this end, a further amount of initiator (dissolved in a solvent) can be added for a period of 0.5 hours and generally up to 3 hours, preferably about 1 hour to 2 hours, more preferably about 1 hour (but this duration also depends on the reactor scale), and the free radical initiator and the solvent for this initiator are generally and preferably the same as those used in the main polymerization reaction. Of course, different free radical initiators and / or different solvents can also be used.
[0450] The temperature of the post-polymerization process step can be the same as that of the main polymerization reaction (which is preferred in the present invention), or it can be increased. In the case of increasing the temperature, it can generally be increased by about 5°C to 40°C, preferably 10°C to 20°C.
[0451] Between the post-polymerization reaction and the main polymerization reaction, a certain period of time can be waited (during which the main polymerization reaction maintains the system conditions and continues), and the post-polymerization reaction is initiated only when the additional free radical initiator starts to be added.
[0452] For solvents with a boiling point of about less than 110°C to 120°C at atmospheric pressure, such solvents can be partially or substantially completely removed (all operations are carried out at atmospheric or reduced pressure, preferably by vacuum distillation) by thermal distillation, vacuum distillation, or stripping with a gas such as steam or nitrogen (such as stripping with water vapor generated by water), while the higher boiling point solvents will generally remain in the resulting polymer product.
[0453] When mercaptoethanol is used as a chain transfer regulator, steam distillation is the preferred purification step. Therefore, when high boiling point solvents such as 1-methoxy-2-propanol, 1,2-propanediol, and tripropylene glycol are used and such solvents are only used to introduce the initiator, such solvents will remain in the polymer product, so their usage should be minimized as much as possible by using the highest possible concentration of free radical initiator; unless such solvents also constitute components of the formulation in which the graft polymer will be used, this reduction treatment is not required.
[0454] The graft polymers of the present invention prepared by the methods defined herein may contain an amount of ungrafted polymer (the "ungrafted side chains") made from vinyl esters, such as polyvinyl acetate made when only vinyl acetate is used, and / or when other monomers are used, homopolymers and copolymers made from vinyl esters and other monomers. The amount of such ungrafted vinyl ester homopolymers and copolymers may be high or low, depending on the reaction conditions, but is preferably reduced and thus low. By this reduction, the amount of the graft side chains is preferably increased. Such reduction can be obtained by suitable reaction conditions, such as the dosage of vinyl esters and free radical initiators and their relative amounts and relative to the amount of the main chain present. Such reaction control and the necessary process steps are common general knowledge to those skilled in the art and specific guidance has been given herein.
[0455] This adjustment of the graft degree and this amount of ungrafted polymer can be used to optimize the properties in areas of particular interest, such as certain (e.g., detergent) formulations, application areas or desired properties such as cleaning.
[0456] It is believed that the conditions considered to be advantageous herein promote (presumably have) a higher graft degree. This higher graft degree is associated with more excellent properties. However, this presumably higher graft degree does not impair the biodegradability performance (which is attributed to the ester bonds in the main chain that can "compensate" for the lower biodegradability performance of the graft polymer with a higher graft degree), a phenomenon that can be seen in "conventional graft polymers" based on polyalkylene oxides as the main chain.
[0457] The disadvantage is that it is extremely difficult (if not completely impossible) to actually verify this graft degree on the polymer, especially when the molecular weight of the polymer increases, because the total amount of graft sites in the polymer is usually very low compared to its molecular weight; therefore, the signal-to-noise ratio of the polymer is low in terms of existing analytical tools.
[0458] In another alternative embodiment of the present invention, the polymer side chains (B) of the graft polymer according to the present invention are completely or partially hydrolyzed after the polymerization reaction, and thus after obtaining the graft polymer itself, preferably partially hydrolyzed, based on the total molar amount of (B1) used, more preferably at most 50 mol%, preferably at least 20 mol%, more preferably 20 mol% to 50 mol%, even more preferably 30 mol% to 45 mol%, such as about 40 mol%. This means that the complete or at least partial hydrolysis of the polymer side chains (B) of the graft polymer is carried out in a further process step after the completion of the polymerization process of the polymer side chains (B) (including after this step if an optional post-polymerization step is employed).
[0459] In another alternative embodiment, after the completion of the polymerization process of the polymer side chains (B), the graft polymer is not subjected to hydrolysis treatment.
[0460] Due to this complete or at least partial hydrolysis of the polymer side chain (B) of the graft polymer according to the invention, the corresponding side chain units derived from at least one vinyl ester monomer (B1) change from the corresponding ester functional groups to alcohol functional groups within the polymer side chain (B). It must be noted that due to the stability problem of the "vinyl alcohol" monomer, the corresponding vinyl alcohol is not suitable as a monomer used in the polymerization process of the polymer side chain (B). In order to obtain alcohol functional groups (hydroxyl substituents) within the polymer side chain (B) of the graft polymer according to the invention, the alcohol functional groups are generally introduced by hydrolyzing the ester functional groups of the side chain.
[0461] From a theoretical perspective, each ester functional group of the polymer side chain (B) can be partially or completely replaced by an alcohol functional group (hydroxyl group). In this case, the polymer side chain is completely hydrolyzed ("saponified").
[0462] The hydrolysis can be carried out by any method known to those skilled in the art. For example, hydrolysis can be induced by adding a suitable base such as sodium hydroxide or potassium hydroxide. This hydrolysis method is known in the prior art.
[0463] In a preferred embodiment among the foregoing embodiments, vinyl acetate is used as the monomer (B1), vinyl pyrrolidone is used as the monomer (B2), and no other monomers are used except (B1) and (B2). The polymer portion derived from vinyl acetate is partially hydrolyzed after the polymerization reaction. Based on the total number of moles of (B1) used, the amount of hydrolysis is preferably 20 mol% to 50 mol%, more preferably 30 mol% to 45 mol%, such as most preferably about 40 mol%.
[0464] The graft polymer of the present invention (i.e., the polymer solution obtained by this process) can also be subjected to means of concentration and / or drying.
[0465] The obtained graft polymer solution can be concentrated by subjecting the polymer solution to means of removing part of the volatile substances (especially the solvent) to increase the solid polymer concentration. This can be achieved by a distillation process (such as thermal distillation or vacuum distillation), or by a stripping method using a gas such as steam or an inert gas (such as nitrogen or argon) until the desired solid content is reached. This process can be combined with the purification step as disclosed before, in which the obtained graft polymer solution is purified by removing part or all of the volatile components (such as volatile solvents and / or unreacted volatile monomers) and removing the required amount of solvent.
[0466] After the graft polymer solution has been subjected to the main polymerization and / or optional post-polymerization step and an optional purification step, it can be further concentrated or dried by the following means: subjecting the graft polymer solution to means for partially or completely removing volatile substances (such as using a distillation process for concentration, such as thermal distillation or vacuum distillation, or stripping with a gas such as steam or an inert gas (such as nitrogen or argon) until the desired solids content is reached), and / or drying, such as drum drying, spray drying, vacuum drying or freeze drying, preferably spray drying (mainly for cost considerations). This drying process can also be used in combination with an agglomeration or granulation process (such as spray agglomeration, granulation or drying in a fluidized bed dryer).
[0467] Therefore, the process of the present invention preferably encompasses at least one additional process step selected from i) to iv), including: i) post-polymerization; ii) purification; iii) concentration; and iv) drying.
[0468] More preferably, the process as detailed in any of the embodiments defined herein includes at least one additional process step selected from the following:
[0469] i) A post-polymerization process step carried out after the main polymerization reaction, in which preferably an additional amount of initiator (optionally dissolved in a solvent) is added over a period of 0.5 hours to a maximum of 3 hours, preferably about 1 hour to 2 hours, more preferably about 1 hour, where the free radical initiator and the solvent for the initiator are generally and preferably the same as those used for the main polymerization reaction; and where after the polymerization reaction is completed and before the post-polymerization reaction is started, preferably a waiting period is allowed for the main polymerization reaction to continue, and then the post-polymerization reaction is initiated by starting to add additional free radical initiator, this waiting period being preferably 10 minutes to a maximum of 4 hours, preferably at most 2 hours, even more preferably at most 1 hour, and most preferably at most 30 minutes; and where the temperature of the post-polymerization process step is preferably the same as or higher than the temperature of the main polymerization reaction, this temperature increase being preferably about 5°C to 40°C higher than the main polymerization reaction temperature, preferably 10°C to 20°C higher.
[0470] ii) Subjecting the graft polymer obtained from the main polymerization process or (if carried out) the post-polymerization process to means for purification, concentration and / or drying to remove some or almost all of the residual solvent (the part that can be removed according to its boiling point) and / or volatile substances (such as residual monomers), where
[0471] a. Concentration is carried out by removing part of the solvent and optionally also removing volatile substances (thus, this step also serves as a purification means) to increase the solid polymer concentration (and optionally also achieve purification). Preferably, a distillation process such as thermal distillation or vacuum distillation (preferably vacuum distillation) is applied, and / or a stripping method using a gas such as steam or an inert gas (such as nitrogen, preferably steam) is applied. This process continues until the desired solid content is reached and optionally also the desired purity is achieved (preferably until the expected part or all of the volatile components (such as volatile solvents and / or unreacted volatile monomers) are removed);
[0472] b. Drying is carried out by subjecting the graft polymer containing at least a residual amount of volatile substances (such as residual solvents and / or unreacted monomers, etc.) to means for removing volatile substances, such as drum drying, spray drying, vacuum drying or freeze drying, preferably (mainly for cost reasons) spray drying; and optionally combining such a drying process step with agglomeration or granulation means to obtain agglomerated or granular graft polymer particles. Such a process is preferably selected from spray agglomeration, granulation or drying in a fluidized bed dryer, a spray granulation device and similar devices.
[0473] Use of the graft polymer.
[0474] In principle, the graft polymers of the present invention can be used in any application to replace conventional graft polymers of the same or very similar compositions (in terms of the relative amounts of the polymer backbone and graft monomers, especially when the type and amount of the graft monomers are similar or equivalent). Such applications include, for example: achieving soil redeposition inhibition and stain removal, preventing or reducing secondary pollution or ash formation or solid deposition or dye redeposition, enhancing the dispersion stability of active substances in a formulation, surface hydrophobization treatment, reducing surface microbial growth, and / or odor control, etc., compared with corresponding polymers or graft polymers according to the prior art.
[0475] The graft polymers of the present invention as defined herein (which can be obtained by the methods as defined herein, or by the methods as defined herein) can increase the total biodegradation rate of such formulations, compositions and products by replacing non-biodegradable polymers with similar structures or properties. Therefore, such graft polymers can be advantageously applied - the application effect also partly depends on the type of monomer B used for grafting, and the performance is adjusted accordingly to meet the specific requirements of a particular application; this monomer substitution pattern may also be deduced from the prior art of similar graft polymers of simple PEG and polyalkylene glycols.
[0476] Specifically, in addition to the performance advantages in specific types of applications, compared with previously known graft polymers, the graft polymers according to the present invention exhibit an improved biodegradation ability when applied to such compositions or products.
[0477] Accordingly, another subject of the present invention is the use of the graft polymers of the present invention and / or graft polymers obtainable or obtained by the method of the present invention and / or graft polymers as detailed above in cleaning compositions, fabrics and home care products, in particular for enhancing the removal of oily and lipid stains, removing solid dirt (such as clay), preventing graying or discoloration of the fabric surface, and / or a cleaning composition as a scale inhibitor, wherein the cleaning composition is preferably a laundry detergent formulation and / or a dishwashing detergent formulation, more preferably a liquid laundry detergent formulation and / or a liquid hand dishwashing detergent formulation.

[0482] Furthermore, these graft polymers also better disperse the removed dirt in the washing or cleaning liquid and prevent it from redepositing onto the surface of the washed or cleaned material. Herein, the removed dirt includes all typical dirt present during the laundry process, such as body soil, food and grease stains, particulate dirt (such as clay or carbon black), grass stains, cosmetics, engine oil, etc. Such anti-redeposition effects can be observed on various fabric types, including cotton, polyester-cotton, polyester, copolymers of polyether / polyurea (Spandex TM) etc. In addition, this anti-redeposition effect is also effective for fabrics with a history of fabric softeners, or when fabric washing is carried out in the presence of fabric softeners or other laundry additives (such as freshness beads or bleaches).

[0506] The composition contains a surfactant system in an amount sufficient to provide the desired cleaning properties. In some embodiments, the composition contains from about 1% to about 70% by weight of the surfactant system, based on the weight of the composition. In other embodiments, the composition contains from about 2% to about 60% by weight of the surfactant system.

Preferred surfactant systems comprise an anionic surfactant and a nonionic surfactant, preferably in a weight ratio of from 90:1 to 1:90. In some cases, a weight ratio of anionic surfactant to nonionic surfactant of at least 1:1 is preferred. However, a ratio below 10:1 can be preferred. When present, the total surfactant level is preferably from 0.1% to 60%, 1% to 50%, or even 5% to 40% by weight of the subject composition.

[0630] Polyester Detergency Polymers.
[0631] The composition can comprise one or more soil release polymers (SRPs).
[0632] Polyester SRPs typically have hydrophilic segments to hydrophilize the surface of hydrophobic fibers such as polyester and nylon, and hydrophobic segments to deposit on and adhere to the hydrophobic fibers until the wash and rinse cycles are complete, thereby acting as an anchor for the hydrophilic segments. This can make stains that appear after treatment with a detergent easier to clean in a later washing process. It is also believed that facilitating soil release helps to improve or maintain the wicking properties of the fabric.
[0633] The structure of the polyester SRP can be tailored to be suitable for different detergent or detergent additive products. The soil release polymer can be linear, branched, or star-shaped. The soil release polymer can also comprise a variety of charged units. Generally, when the SRP is used in combination with a detergent containing an anionic surfactant, a nonionic SRP or an anionic SRP can be particularly preferred to avoid potential negative interactions between the SRP and the anionic surfactant. The soil release polymer can comprise end-capping moieties that are particularly effective in controlling the molecular weight of the polymer or altering the physical or surface adsorption properties of the polymer.

[0814] Typically, a washing liquid is formed by contacting a laundry washing and care composition with a certain amount of wash water such that the concentration of the laundry detergent care composition in the washing liquid is 0 g / l or more up to 5 g / l, or 1 g / l and up to 4.5 g / l, or up to 4.0 g / l, or up to 3.5 g / l, or up to 3.0 g / l, or up to 2.5 g / l, or even up to 2.0 g / l, or even up to 1.5 g / l. The method of washing a laundry fabric or textile can be carried out in a top-loading or front-loading automatic washing machine or can be used in a hand laundry washing application. In these applications, the washing liquid formed and the concentration of the laundry detergent composition in the washing liquid are those in the main wash cycle. During any optional one or more rinsing steps, when determining the volume of the washing liquid, any added water is not included.
[0815] The washing liquid can contain 40 liters or less of water, or 30 liters or less, or 20 liters or less, or 10 liters or less, or 8 liters or less, or even 6 liters or less of water. The washing liquid can contain from more than 0 liters up to 15 liters, or 2 liters and up to 12 liters, or even up to 8 liters of water. It is typically added to the washing liquid at a dosage of 0.01 kg to 2 kg of fabric per liter of washing liquid. It is typically added to the washing liquid at a dosage of 0.01 kg, or 0.05 kg, or 0.07 kg, or 0.10 kg, or 0.15 kg, or 0.20 kg, or 0.25 kg of fabric per liter of washing liquid. Optionally, 50 g or less, 45 g or less, 40 g or less, 35 g or less, 30 g or less, 25 g or less, 20 g or less, even 15 g or less, or even 10 g or less of such a composition is contacted with water to form the washing liquid. Such compositions are typically used at a concentration of about 500 ppm to about 15,000 ppm in solution. When the washing solvent is water, the water temperature is typically in the range of about 5°C to about 90°C, and when the portion contains fabric, the ratio of water to fabric is typically about 1:1 to about 30:1. Typically, the washing liquid containing the laundry washing and care composition of the present invention has a pH of 3 to 11.5.
[0816] In one aspect, such a method comprises the steps of optionally washing and / or rinsing a surface or fabric, contacting the surface or fabric with any of the compositions disclosed in this specification, then optionally washing and / or rinsing the surface or fabric, and an optional drying step.
[0817] Drying of such surfaces or fabrics can be achieved by any of the common methods employed in household or industrial settings. The fabric can include any fabric capable of being laundered under normal consumer or institutional use conditions, and the present invention is applicable to cellulose substrates and, in some aspects, also to synthetic textiles such as polyester and nylon, and is applicable to treating mixed fabrics and / or fibers comprising synthetic and cellulose fabrics, and / or fibers. Examples of synthetic fabrics are polyester, nylon, which can be present in a mixture with cellulose fibers, such as a polyester-cotton fabric. The solution typically has a pH of 7 to 11, more typically 8 to 10.5. The composition is generally used at a concentration of 500 ppm to 5,000 ppm in the solution. The water temperature is typically in the range of about 5°C to about 90°C. The ratio of water to fabric is generally about 1:1 to about 30:1. Another method involves contacting a soiled material with a nonwoven substrate impregnated with a detergent composition. As used herein, "nonwoven substrate" can include any conventional style of nonwoven sheet or web having suitable basis weight, thickness (thick), absorbency, and strength characteristics. Non-limiting examples of suitable commercially available nonwoven substrates include those sold by DuPont under the trade name and those sold by JamesRiver Corp. under the trade name POLY .
[0818] Carbon Source of Raw Materials.
[0819] The raw materials used to prepare surfactants, polymers, and other ingredients can be based on fossil carbon or renewable carbon. Renewable carbon is a carbon source that avoids the use of fossil carbon, such as natural gas, coal, and petroleum. Generally, renewable carbon is derived from biomass, carbon capture, or chemical recycling.
[0820] Biomass is a renewable carbon source formed through photosynthesis in the presence of sunlight or through a chemical synthesis process in the absence of sunlight. In some cases, polymers isolated from biomass can be used directly or further derivatized to prepare performance polymers. For example, the use of polysaccharides (such as starch) and derivatized polysaccharides (such as cellulose derivatives, guar gum derivatives, dextran derivatives) in fabric home care compositions is known. In some cases, biomass can be converted into basic chemicals under certain thermal, chemical, or biological conditions. For example, bioethanol can be derived from biomass such as straw and further converted into bio-based polyethylene glycol. Other non-limiting examples of renewable carbon from biomass include plants (such as sugarcane, beets, corn, potatoes, citrus fruits, woody plants, lignocellulose, hemicellulose, cellulose waste), animals, animal fats, fish, bacteria, fungi, plant-based oils, and forestry products. These resources can be naturally occurring, hybrids, or genetically engineered organisms.
[0821] Carbon capture is another renewable carbon source that uses various methods to capture CO2 or methane (direct capture) from industrial or natural processes, or directly from the air. The captured methane and CO2 can be converted to syngas and / or further converted to basic chemicals, including but not limited to methanol, ethanol, fatty alcohols such as C 12 / C 14 or even C 16 / C 18 alcohols, other alcohols, olefins, alkanes, saturated and unsaturated organic acids, etc. These basic chemicals can be used as monomers or further converted to monomers for conversion to useful chemicals by, for example, catalytic methods such as the Fischer-Tropsch process or by fermentation of C1-fixing microorganisms.
[0822] Chemical recycling is another renewable carbon source that allows plastics from the waste management industry to be recycled and converted into basic chemicals and chemical feedstocks. In some cases, waste plastics that cannot be reused or mechanically recycled are converted into hydrocarbons or basic petrochemical products through gasification, pyrolysis, or hydrothermal treatment processes, and the hydrocarbons and basic petrochemical products can be further converted into monomers for polymers. In some cases, waste plastics are depolymerized into monomers to prepare new polymers. Waste plastics can also be depolymerized into oligomers, which can be used as building blocks for manufacturing new polymers. Waste plastics from waste plastic raw materials converted into the above materials can be used alone or in combination with traditional surfactant raw materials (such as kerosene, polyolefins derived from natural gas, coal, crude oil, or even biomass, or paraffins and olefins derived from waste fats / oils) to produce biodegradable surfactants for detergents and other industries (thus providing beneficial effects to society).
[0823] Preferably, the surfactants, polymers, and other components contain renewable carbon, and the renewable carbon index (RCI, a measure of sustainability obtained by dividing the number of carbons from renewable sources by the total number of carbons in the active ingredient) of the polymer is higher than 10%, more preferably higher than 30%, more preferably higher than 50%, more preferably higher than 60%, more preferably between 70% and 100%, and most preferably 100%.

[0838] General Synthesis Method of Main Chains A, C, H, I, and J (Table 5):
[0839] Caprolactone is oligomerized prior to the polymerization of the alkylene oxide to form a mixed random / block structure, and the main chain is obtained by the alkoxylation reaction of the polycaprolactone.
[0840] Such polycaprolactones can be obtained by polymerizing caprolactone onto a starter having 2 hydroxy groups, such as a diol, such as ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, ethylene oxide and propylene oxide block copolymers, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, etc.
[0841] The polymerization reaction of caprolactone is carried out in the presence of various catalysts, such as the transesterification catalyst tin(II) alkanoate.
[0842] The alkoxylation reaction of such polycaprolactones is carried out under typical alkoxylation conditions. Since alkoxylation needs to be carried out under basic reaction conditions, transesterification may occur at the ester bond in the polycaprolactone, thereby obtaining a mixed random / block structure.

[0846] General Synthesis Method of Main Chains B, D, E, F, and G (Table 6):
[0847] Caprolactone is added after the alkylene oxide polymerization to form a block structure, namely polycaprolactone - polyalkylene oxide - polycaprolactone.
[0848] A triblock copolymer having an intermediate polyalkylene oxide block, with caprolactone and alkylene oxide as raw materials, and its synthesis method includes: 1. reacting a diol or water with an alkylene oxide to form a polyalkoxylate; and 2. polymerizing and grafting caprolactone onto the polyalkoxylate.
[0849] These two reactions can be carried out respectively under the typical reaction conditions of alkoxylation reaction (to form polyalkoxylate) and the typical reaction conditions of caprolactone polymerization (to form polycaprolactone block).
