Description

[Technical field]

[0001] The present invention relates to oligomers or polymers that are particularly suitable as stabilizers for organic materials, or to compositions containing said oligomers or polymers, and also to intermediates for the synthesis of said oligomers or polymers.

[0002] Organic materials such as plastics are subject to ageing processes that ultimately result in the loss of desired properties, such as, for example, mechanical property values. This process is called autoxidation and leads to changes in the polymer chains, such as, for example, molecular weight, or the formation of new chemical groups resulting from the scission of radical chains, by UV irradiation in the presence of oxygen or by mechanochemical processes. Stabilizers are therefore used to prevent or at least slow down said ageing. Important representatives of stabilizers are antioxidants, which interfere with the free radicals generated during autoxidation and hinder the decomposition process. A distinction is usually made between primary antioxidants, which can react directly with oxygen-containing free radicals or C radicals, and secondary antioxidants, which react with the intermediately generated hydroperoxides (see C.Krohnke et al., Antioxidants in Ullmann's encyclopedia of industrial chemistry, Wiley-VCH Verlag, Weinheim 2015). Typical representatives of primary antioxidants are, for example, phenolic antioxidants, amines, but also lactones. Classes of secondary antioxidants are phosphorus compounds, e.g., phosphites and phosphonites, but also organosulfur compounds, e.g., thioethers or disulfides. Usually in practice, primary and secondary antioxidants are often combined, resulting in a synergistic effect.

[0003] Plastics made from fossil raw materials such as crude oil and natural gas are increasingly being supplemented or replaced by plastics based on renewable raw materials available through biotechnological processes, but the primary and secondary antioxidants used for them (and for plastics produced from fossil raw materials) are not yet extensively based on renewable raw materials.

[0004] A further challenge for antioxidants, especially those used in food applications and in plastics at high temperatures, is to keep migration from the plastic and volatility of the product in which they are used as low as possible without adversely affecting efficacy.

[0005] Basically, primary antioxidants made from renewable raw materials are known and are sometimes used in plastics. A typical example is tocopherol (vitamin E). Like common antioxidants, tocopherol has a sterically hindered phenolic structure and can be used alone or in combination with secondary antioxidants (e.g. S. Al Malaika, Macromol. Symp. 2001, 176, 107). For example, tocopherol can be isolated from natural substances such as wheat germ oil, sunflower oil or olive oil. Other well-known phenolic antioxidants from natural substances that have proven antioxidant effects in polymers are, for example, quercetin, hyperin, rutin, dihydromyrecetin, silymarin, curcumin, rosmarinic acid or cardanol.

[0006] Materials with high molecular weight, especially oligomers or polymers, can preferably be used to reduce the migration and volatility of the antioxidant.

[0007] The preparation and effectiveness of such antioxidants are described, for example, in the following patents: EP 2 061 829 (Preparation of liquid polymeric phosphites and phosphonites for use as stabilizers) EP 0 685 519 (Oligomeric HALS-phosphites and HALS-phosphonites as stabilizers)

[0008] However, the known oligomeric and polymeric antioxidants are not based on renewable raw materials and / or do not contain a 6-hydroxychroman core.

[0009] It was therefore an object of the present invention to provide effective oligomeric and polymeric antioxidants which are based partly or largely on renewable raw materials.

[0010] This object is achieved with respect to an oligomer or polymer comprising a phosphorus-containing structural element having the features according to claim 1, with respect to a composition thereof comprising said oligomer or polymer and an organic component to be stabilized having the features according to claim 8, with respect to possible uses of the inventive oligomer or polymer having the features according to claim 13, with respect to moulding compounds or moulded parts having the features according to claim 15 and with respect to intermediates suitable for synthesising the inventive oligomer or polymer having the features according to claim 16. The respective dependent claims represent advantageous developments.

[0011] The present invention therefore relates to oligomers or polymers which comprise a structure according to general formula I as a structural element. [ka] Here, R 1 is defined by the following formula II [ka] where R is the same or different at each occurrence and is selected from the group consisting of hydrogen or a linear or branched alkyl radical having 1 to 36 carbon atoms; and x is 0 or 1.

[0012] For the purposes of the present invention, the terms oligomer or polymer are generally used according to the definition established by IUPAC as defined in Pure Appl. Chem. 2016;88(10-11):1073-1100.

[0013] In particular, oligomers are understood to be molecules having 3 to 10 repeat units, and polymers are understood to be molecules having more than 10 repeat units, which usually results in an average molecular weight (number average) of about 1000 to 4000 for oligomers and more than 4000 for polymers.

[0014] Surprisingly, it has been found that the oligomers or polymers of the invention are highly effective.

[0015] According to a preferred embodiment, R 1 is defined according to formula IIa below: [ka]

[0016] A further preferred embodiment provides that the oligomer or polymer comprises the following repeat unit according to formula III: [ka] where D is the same or different for each occurrence and is functionality derived from a diol.

[0017] Here, the functional group derived from a diol is preferably a functional group derived from an aliphatic, aromatic, or heterocyclic diol.

[0018] According to an exemplary embodiment, the functional groups derived from the diol are as follows: a) functional groups derived from aliphatic diols, preferably functional groups derived from ethylene glycol, 1,3-propylene glycol, 1,2-propylene glycol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,8-octanediol, 1,10-decanediol, 1,12-dodecanediol, 1,4-cyclohexanediol, 1,3-cyclohexanediol and / or 1,4-cyclohexanedimethanol, b) Functional groups derived from aromatic diols, preferably those derived from hydroquinone, resorcinol, 1,5-, 2,6- or 2,7-dihydroxynaphthalene, vanillyl alcohol or the following diols: [ka] where, independently of each other, A is a direct bond, -O-, -SO 2 -, -C(O)-, -CH(CH 3 )- or -C(CH 3 ) 2 - means, and R' and R'' are the same or different at each occurrence and are selected from the group consisting of linear or branched alkyl moieties having 1 to 36 carbon atoms; c) a functional group derived from a heterocyclic diol, preferably derived from hydroxyethyl-4-hydroxytetramethylpiperidine, 1,4-dithiane-2,5-diol, or d) Functional groups derived from the following diols: 2,3-Dimethoxy-1,4-butanediol [ka]

[0019] According to a further embodiment of the invention, the oligomer or copolymer is a cooligomer or copolymer, i.e. comprises at least two different repeat units based on a repeat unit according to formula I.

[0020] The embodiment provides, for example, that the oligomer or polymer has the following repeat units according to formula I, which correspond to the following definitions according to formulae III and IIIa: [ka] Here, R 1 , D and x are as defined above, and the definition of D' corresponds to the definition of D, with the proviso that D and D' are derived from different diols.

[0021] For example, the group D derived from a diol as used in formula III above may be selected from one or more diols as described in a) or b) above.

[0022] The group D' derived from a diol can be, for example, a diol selected from the diols as described above under c).

[0023] For example, the molar ratio of repeating units III:IIIa can be from 0.1:99.9 to 50:50, preferably from 0.5:99.5 to 10:90.

[0024] The oligomer or polymer preferably comprises only repeat units according to formula I, where x = 0. Alternatively, the oligomer or polymer can comprise both repeat units of formula I, where x = 0, and repeat units of formula I, where x = 1, where the molar ratio of repeat units of formula I, where x = 0: repeat units of formula I, where x = 1 is from 50:50 to <100:>0, preferably from 90:10 to 99.9:0.1.

[0025] The present invention also relates to a composition comprising at least one organic component to be stabilized and at least one oligomer or polymer according to the invention as described above.

[0026] For example, the composition can be provided to contain at least one oligomer or polymer in a weight ratio of the total composition of 0.01 to 5.0 parts by weight, preferably 0.02 to 2.0 parts by weight, and particularly preferably 0.05 to 1.0 parts by weight.
