Definitions
- the present invention relates to polymeric stabilizers based on renewable raw materials, such as syringic acid, vanillic acid, isovanillic acid or 5-hydroxyveratric acid, a plastic composition, a method for stabilizing a plastic composition and a stabilizer composition with a high stabilizing effect.
- renewable raw materials such as syringic acid, vanillic acid, isovanillic acid or 5-hydroxyveratric acid
- Organic materials such as plastics are subject to aging processes, which ultimately lead to a loss of desired properties such as mechanical properties.
- This process called autoxidation, leads to starting from radical chain scissions by mechanochemical processes or by UV radiation in the presence of oxygen to changes in the polymer chain, such as molecular weight and / or the formation of new chemical groups.
- Stabilizers are therefore used to prevent or at least delay this aging.
- Important representatives of stabilizers are antioxidants, which interfere with the free radicals formed during autoxidation and thus interrupt the degradation process.
- primary antioxidants which can react directly with oxygen-containing free radicals or C-radicals
- secondary antioxidants which react with intermediately formed hydroperoxides (see C. Kröhnke 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 such as phosphites and phosphonites, but also organo-sulphur compounds such as thioesters, thioethers and disulfides.
- primary and secondary antioxidants are often combined, resulting in a synergistic effect.
- Plastics made from fossil raw materials such as crude oil or natural gas are increasingly being supplemented or replaced by plastics based on renewable raw materials via biotechnological processes.
- the question of sustainability then also arises for the primary and secondary antioxidants used for this (and for plastics made from fossil raw materials).
- stabilizers based on renewable and available raw materials that are highly effective, have low volatility and are compatible with polymeric substrates.
- the antioxidants also have photo-oxidation protection to protect the polymers in outdoor applications.
- antioxidants from renewable raw materials are known, which are also occasionally used in plastics.
- a typical example are tocopherols (vitamin E).
- tocopherols have a sterically hindered phenol structure and can be used alone or in combination with secondary antioxidants (e.g. S. Al-Malaika, Macromol. Symp. 2001, 176, 107).
- Tocopherols are isolated from natural substances such as wheat germ oil, sunflower oil or olive oil.
- Other well-known phenolic antioxidants from natural substances that have been investigated in plastics are described, for example, in the following references:
- Tannin (WJ. Grigsby et al., Esterification of condensed tannins and their impact on the properties of poly (lactic acid), Polymers 5 (2013) 344-360),
- WO 98/18830 discloses polymeric stabilizers which also act as compatibilizers and describe, by polymer-analogous reaction, inter alia, sterically hindered phenols, sterically hindered amines, lactones, phosphites with polymers, inter alia, with acrylic acid, glycidyl methacrylate, maleic anhydride and vinyl alcohol.
- M.Rostagno et al. describe in "Sustainable polyvinyl acetals from bioaromatic aldehydes", Polym. Chem. 2017, 8, 5049-5059, Polyacetals Obtained from Aldehydes.
- the structures are complex to synthesize, the compounds obtained are sensitive to hydrolysis, and use as stabilizers is not described.
- CN 110183912 describes a floor coating that contains, among other things, 3,5-dimethoxy-4-hydroxycinnamic acid as a reaction component and, among other things, polyvinyl alcohol.
- the phenol group reacts and is therefore no longer available for antioxidant properties. There are no indications of antioxidant properties.
- polyesters e.g. made from ferulic acid with (poly)ethylene glycol, which are used in a hydrogel that can contain polyvinyl alcohol, among other things.
- the object of the present invention is therefore to provide effective antioxidants for plastics from renewable raw materials which at the same time have very low volatility and/or a low tendency to migrate
- the present invention relates to a plastic composition that contains the specified polymers as stabilizers.
- the present invention further relates to a method for stabilizing a plastic composition using the polymers according to the invention.
- the present invention relates to a stabilizer composition consisting of the polymers according to the invention and at least one additive.
- the present invention relates to a polymer having a repeating unit (A) of the general formula I contains where
- R 1 , R 2 and R 3 are each independently selected from the group consisting of hydroxy, linear or branched alkoxyl groups having 1 to 6 carbon atoms and hydrogen, with the proviso that at least one of the radicals R 1 , R 2 and R 3 is a hydroxy radical and at least one of the radicals R 1 , R 2 and R 3 is a linear or branched alkoxy group having 1 to 6 carbon atoms, where R 1 , R 2 and R 3 are the same or different on each occurrence,
- the polymer can contain the repeating unit (A) according to the formula I ten. This means that, in addition to the repeating unit (A) of the formula I, other repeating units that differ from the repeating unit (A) of the formula I can also be present.
- the polymer according to the invention is a copolymer.
- the repeating unit (A) of the formula I represents the only repeating unit
- the polymer according to the invention is a homopolymer.
- the copolymers can be in the form of random, gradient, alternating or block copolymers.
- the polymers according to the invention not only have an excellent stabilizing effect on plastic materials, but also that the polymers according to the invention have very low volatility and can be produced primarily on the basis of renewable raw materials.
- ester derivatives of polyvinyl alcohol polymers or polyvinyl alcohol copolymers which contain alpha-methoxy-substituted phenols as active components were thus achieved in particular by using ester derivatives of polyvinyl alcohol polymers or polyvinyl alcohol copolymers which contain alpha-methoxy-substituted phenols as active components.
- R 1 is hydrogen, hydroxy or a linear or branched alkoxyl group having 1 to 6 carbon atoms, in particular methoxy,
- R 2 is hydroxy
- R 3 is a linear or branched alkoxyl group having 1 to 6 carbon atoms, especially methoxy.
- ester residues of the repeating unit of the general formula I are derived in particular from naturally occurring compounds such as b) vanillic acid c) isovanillic acid omovanillic acid) e) homosyringic acid f) 3,4-dihydroxy-5-methoxy-benzeneacetic acid g) dihydroferulic acid j) 3,4-dihydroxy-5-methoxy-benzenepropionic acid, m) protocatechuic acid n) gallic acid o) 3,4,5-trihydroxycinnamic acid p) caffeic acid q) dihydrocaffeic acid

- the acids used above as starting materials such as syringaic acid, vanillic acid, isovanillic acid or 5-hydroxyveratric acid are commercially available.
- acids or acid derivatives used as starting materials are commercially available or accessible by known methods, e.g. by base- or acid-catalyzed esterification with alcohols.
- esters of vinyl alcohol can be prepared, for example, by reaction with the acids in the form of a polymer-analogous reaction with acidic catalysis, for example in the presence of sulfuric acid or p-toluenesulfonic acid in a suitable solvent or suspending agent, such as toluene, with the water formed being removed, for example by distillation.
- Another possibility is a process in which a short-chain ester such as the methyl ester or the ethyl ester of the respective acid is first prepared and in a second stage a transesterification reaction with the polyvinyl alcohol in the presence of a suitable catalyst such as dibutyltin butoxide, dioctyltin diacetate, dioctyltin ketonate or tetrabutyl titanate , tetra isobutyl titanate, tetrapropyl orthotitanate.
- a suitable catalyst such as dibutyltin butoxide, dioctyltin diacetate, dioctyltin ketonate or tetrabutyl titanate , tetra isobutyl titanate, tetrapropyl orthotitanate.

- a possible protective group is, for example, the triethylsilyl group, which can be introduced using triethylsilane.
- the polymer according to the invention can, for example, be built up exclusively from the same repeating units (A). It is also possible for the polymer to be built up exclusively from repeating units (A), but in this case at least two different repeating units (A) that can be subsumed under formula I (e.g. due to a different substitution pattern of the radicals R 1 to R 3 ) are present.
