[0042] The copolymer can be prepared by a method including the following processes:
[0043] 1) Copolymerize the starting materials, said starting materials comprising
[0044] 80% to 98.75% by weight of (A) Crystallizable monomers, wherein R 1It is an alkyl group with 16 to 24 carbon atoms as described above, and R 2 Select from the group consisting of H and methyl groups, as described above;
[0045] 0.25% to 15% by weight of (B) Organosilicon-(meth)acrylate macromonomers, wherein each R 3 It is the formula OSi(R) 4 )3 groups; each R 4 Independently select R and DSi(R) 5 The group consists of 3 groups, where each R is an independently selected monovalent hydrocarbon group of 1 to 12 carbon atoms; each D is independently selected from a group consisting of an oxygen atom, 1 to 12 units of (poly)alkyleneoxy groups, and 2 to 4 divalent hydrocarbon groups; each R 5 Independently select R and DSi(R) 6 A group consisting of 3 groups; where each R 6 Independently select a group consisting of R and DSiR3; the prerequisite is as described above, R 4 R 5 and R 6 It was chosen to ensure that each molecule of the macromolecular monomer has at least 6 silicon atoms;
[0046] 1% to 5% by weight of (C) crosslinkable (meth)acrylate monomers of the following formula: R 7 Independently selected from oxygen and NH, D 3 It is a divalent hydrocarbon group with 1 to 12 carbon atoms, D 4 It is a divalent group with 2 to 4 carbon atoms, with subscripts v from 0 to 12, and R 8 These are cross-linking groups, each as described above;
[0047] (D) Surfactants;
[0048] (E) Water;
[0049] (F) Initiator;
[0050] (H) chain transfer agent;
[0051] (K) manganese ion source; and
[0052] (L) Phenolic compounds;
[0053] This results in an aqueous emulsion containing (I) an organosilicon-(meth)acrylate copolymer, (D) a surfactant, (E) water, (K) a manganese ion source, and (L) a phenolic compound.
[0054] In step 1), the above emulsion polymerization method may include forming an emulsion comprising starting materials (A), (B), (C), (D), (E), (K), and (L) (and optionally (H) and / or (J)), and then adding initiator (F) and copolymerizing. It is not intended to be theoretically rigorous, but it is thought that during the processing to combine and emulsify (A), (B), (C), (D), (E), (H), and (J), the starting materials (K) and (L) may inhibit the formation of acrylic acid radicals, which may affect copolymer formation during copolymerization in step 1).
[0055] A method for preparing an emulsion formulation suitable for the preparation of textiles may include performing step 1) above to form a first aqueous emulsion comprising an organosilicon-(meth)acrylate copolymer, a surfactant, water, a manganese ion source, and a phenolic compound; and 2) combining the first aqueous emulsion prepared in step 1) with a second aqueous emulsion comprising (II) an additive (as described above and in detail below), (III) a water-dispersible crosslinking agent (as described above and in detail below) and optionally one or more additional starting materials.
[0056] Alternatively, one or more additional starting materials may be added in step 1) to prepare the copolymer. For example, in step 1), an additional non-crystallizable monomer (J) may be added, which is different from each of (A), (B) and (C).
[0057] Step 1) of the above method may include forming an emulsion comprising starting materials (A), (B), (C), (D), (E), (F), (H), (K), and (L) (and optionally (J)). If the starting material (A) is solid at RT, the starting material may be heated to a temperature and time sufficient to melt the starting material (A), for example, 30°C to 50°C for 5 to 15 minutes. The resulting starting materials may be mixed under shear to form an aqueous emulsion. Shear mixing may be performed by any convenient means for forming an aqueous emulsion, such as ultrasonic treatment and subsequent microfluidization. Equipment for shear mixing (such as ultrasonicators, homogenizers, microfluidizers, and high-speed mixers) is known in the art and is commercially available. It is not intended to be theoretically construed that shear mixing can be used to obtain submicron particle sizes in emulsions. In step 1), the starting materials comprising (A), (B), (C) and (F) (and, when present, (H) and (J)) are copolymerized with the starting materials (D), (E), (K) and (L) in an aqueous emulsion to form (I) organosilicon-(meth)acrylate copolymer.
[0058] Step 2) of the above-described method for preparing emulsion formulations can be carried out in any convenient manner, such as mixing in a jacketed container equipped with a stirrer. Steps 1) and 2) can be carried out sequentially in the same container. Alternatively, steps 1) and 2) can be carried out in different devices. Steps 1) and / or 2) can be carried out at RT or at elevated temperatures (e.g., up to 100°C, alternatively 40°C to 80°C). Alternatively, heating can be carried out in step 1), and step 2) can be carried out at RT. Alternatively, one or both of steps 1) and 2) can be carried out at lower temperatures and elevated pressures (e.g., up to 5 atmospheres).
[0059] Prior to step 1), the starting materials comprising (A), (B), (C), (H), (K), (L), and (J) if present, can be combined under aerobic or anaerobic conditions, optionally heated for an extended time. For example, prior to the addition of the initiator and copolymerization in step 1), the starting materials comprising (A), (B), (C), (H), (K), (L), and (J) if present, can be emulsified with (D) and (E). In step 1), the starting materials are combined in the above method, and copolymerization can be carried out on a commercial scale under anaerobic or aerobic conditions, optionally at elevated temperatures (e.g., up to 100°C, alternatively 40°C to 80°C, and alternatively 45°C to 50°C). Copolymerization can be carried out in a batch manner, wherein the residence time is 15 minutes to 24 hours, alternatively 30 minutes to 12 hours, alternatively 40 minutes to 8 hours, and alternatively 40 minutes to 2 hours. For the purposes of this application, aerobic or anaerobic conditions mean that oxygen does not need to be present in the gas in the headspace of the reactor where copolymerization occurs, or dissolved in the liquid where copolymerization occurs. The remaining gas in the headspace can be an inert gas, such as nitrogen or argon.
[0060] Alternatively, compositions comprising the above-described copolymers, manganese ion sources, and phenolic compounds can be prepared by a method comprising dissolving one or more starting materials such as (A), (B), (C), (H), (K), (L), and (J) if present) in an organic solvent (such as a monohydric alcohol), and copolymerizing the starting materials (A), (B), (C), (F), (H), and (J) if present) by varying suitable starting materials and their amounts, such as in the method disclosed in U.S. Patent 10,047,199 to Iimura et al. The resulting compositions may be solvent-based. All or part of the solvent may be removed by any convenient means, such as by stripping or heated distillation and optionally by reduced pressure. The resulting compositions comprising the copolymers, manganese ion sources, and phenolic compounds may be emulsified using (D) a surfactant and (E) water. The starting materials for preparing the compositions and the emulsion formulations comprising the compositions are further described below.
[0061] The starting material (A) is a crystallizable monomer of formula (A-1): , where R 1 and R 2 As described above. Examples of crystallizable monomers used for starting material (A) include octadecyl (meth)acrylate, eicosyl (meth)acrylate, docosyl (meth)acrylate, and combinations thereof. Alternatively, when R 2 When hydrogen is present, the starting material (A) can be an acrylate selected from octadecyl acrylate, eicosyl acrylate, docosyl acrylate, and combinations thereof. Crystallizable monomers suitable for the starting material (A) are commercially available, for example, from Millipore Sigma, St. Louis, Missouri, USA, and BASF SE, Ludwigshafen, Germany. Crystallizable means that the starting monomer has a melting point of ≥25°C ± 5°C.

Examples of processes that can be used to purify water include distillation, filtration, deionization, and combinations of two or more of these, such that water can be deionized, distilled, and / or filtered. Alternatively, the water can be untreated (e.g., tap water, i.e., supplied by a municipal water supply or well water, used without further purification). The amount of water is sufficient to form an aqueous emulsion for emulsion polymerization in step 1) of the method described above. Additional water may be added after step 1). For example, the first aqueous emulsion and / or the second aqueous emulsion prepared as described above may be diluted with additional water to obtain the desired amount of starting material before treating textiles with the emulsion formulation. In step 1), water may be added in amounts of 20% to 97%, alternatively 30% to 90%, alternatively 40% to 80%, alternatively 50% to 97%, alternatively 50% to 90%, or alternatively 60% to 80%, based on the combined weight of all starting materials in step 1).

[0083] Without being bound by theory, it is assumed that starting materials (A), (B), and (C), and (if present) (J), copolymerize to form (I) organosilicon-(meth)acrylate copolymer as described herein with starting material (I). Furthermore, it is assumed that starting material (D), surfactant, and (E), water, do not participate in the copolymerization reaction; however, copolymers including one or both of starting materials (D) and (E) are not excluded from the scope of this document.

Alternatively, the silicone-(meth)acrylate copolymer can be a reaction product of a starting material consisting of starting materials (A), (B), (C), and (F) (and, when present, (H) chain and / or (J)). It is not desirable to be bound by theory, but rather to consider that starting materials (D) and (E) do not copolymerize with starting materials (A), (B), and (C), but only act as mediators for copolymerization. However, the possibility that one or more of the starting materials (D) and / or (E) or any other starting material added during the method may participate in the copolymerization reaction of the starting materials (A), (B), (C) and (F) should not be excluded in this paper.
[0086] In emulsion formulations suitable for treating textiles, the (I) silicone-(meth)acrylate copolymer may be present in an amount ranging from 57.2% to 88.5% based on the combined weight of all starting materials other than water in the emulsion formulation.

The exact amount of crosslinking agent (III) depends on various factors, including the type and amount of the silicone-(meth)acrylate copolymer (I) formed in step 1) and the textile to be treated; however, based on the weight of the fabric, the weight of crosslinking agent (III) may be sufficient to provide 0.25% to 3.75%, alternatively 0.25% to 1%, and alternatively 0.25% to 0.5% on the same basis.

Alternatively, when the textile to be treated is polyamide such as nylon, the combination may be present in an amount of 0.8% to 28.5%.
[0115] When selecting starting materials to add to the first and second aqueous emulsions described above, and to emulsion formulations suitable for treating textiles, there may be overlap between the types of starting materials, as some of the starting materials described herein may have more than one function.

[0117] Additional starting materials may be optionally used in the above methods. For example, chelating agents may be used when preparing copolymers.
[0118] Methods for treating textiles
[0119] The emulsion formulation prepared as described above can be used to treat textiles. For example, methods for treating textiles include: I) coating the textiles with the emulsion formulation described above, and II) heating the textiles. Step I) can be carried out by any convenient method, such as padding, impregnating, or spraying the textiles with the emulsion formulation. However, based on the weight of the textiles, the method should be sufficient to deliver 0.25 wt% to 7.5 wt% of (I) silicone-(meth)acrylate copolymer, 0.01 wt% to 0.5 wt% of (II) additive, and 0.05 wt% to 0.5 wt% of (III) water-dispersible crosslinking agent, based on the weight of the fabric. When the (II) additive is a combination of (II-2), the amount of (I) silicone-(meth)acrylate copolymer and the amount of the (II-2) combination are sufficient to provide a (I):(II-2) weight ratio of 2:1 to <200:1.
[0120] Step II) can be performed by any convenient method, such as placing the textile in an oven. The textile may be heated to remove all or part of the water and / or cure the emulsion formulation. The exact temperature depends on various factors, including the temperature sensitivity of the type of textile selected and the required drying time. However, heating may be performed at temperatures >100°C to remove water. Alternatively, the temperature may be >100°C to 200°C for a duration sufficient to remove all or part of the water, deseal the end-capped isocyanate crosslinking agent, and / or cure (I) the silicone-(meth)acrylate copolymer and (II) the additive.
[0121] There are no particular limitations on the textiles to be treated. Suitable textiles include naturally derived textiles, such as fabrics of cotton, silk, linen, and / or wool; textiles derived from synthetic sources, such as rayon, acetate, polyester, polyamides (such as nylon), polyacrylonitrile, and polyolefins (such as polyethylene and / or polypropylene), and combinations of two or more of these (e.g., blends such as polyester / cotton blends). There are also no particular limitations on the form of the textiles. The emulsion formulations described herein are suitable for any form of textile, such as woven fabrics, knitted fabrics, carpets, or nonwoven textiles.
[0122] Durable water resistance test :
[0123] The Bundesmann test was performed using the ISO 9865 method. Facial rating data were collected after 0, 1, 10, and 20 washes using an SDL Atlas M230 Bundesmann test apparatus. The instrument was calibrated so that the amount collected per cup after 150 seconds was between 190 mL and 210 mL. Facial ratings were assigned based on images from the ISO 9865 method, using half-increments as intermediate allocations. Facial ratings were repeatable and reported as averages. Acceptable values were ≥4.5 to 5.
[0124] Problems to be solved
[0125] Organosilicon-(meth)acrylate hybrid copolymers can impart excellent and durable water resistance to various textiles; however, they may have the drawback of imparting rigidity, negative aesthetics, and poor hand feel. Known compositions for treating textiles, such as those disclosed in U.S. Patent Application Publication 2020 / 0332148, can impart sufficient aesthetics but may provide insufficient durable water resistance for some applications. Furthermore, there is a need to produce commercially viable non-fluorocarbon-based textile treatment agents that can stabilize monomer emulsions at higher temperatures for extended treatment times while maintaining excellent performance properties.
[0126] solution
[0127] Without being bound by theory, this invention provides an emulsion formulation that, when used to treat textiles, imparts softness and hand feel as well as good, durable water resistance, as measured by the Bundesmann test described herein. More specifically, the fabric can have a Bundesmann face rating of ≥4.5 after initial treatment and retain a face rating of ≥4.5 after 1 wash, 5 washes, 10 washes, and 20 washes. Without being bound by theory, it is believed that the use of a manganese ion source and phenolic compounds will result in better monomer emulsion stability and will impart improved post-polymerization water resistance to the fabric (compared to monomer emulsions that do not contain one or both of the manganese ion source and phenolic compounds).
