Description

FUNCIOMAI-IZADOS POLYMERS The present invention relates to the establishment of plastics and plastic compositions ° (virgin or recycled materials, optionally combined with virgin materials) and at the same time to the improvement of mechanical properties by the incorporation of specific compatibilizers. The preparation of polymer blends is an established method for producing plastics that have novel properties. As is known, however, polymers of different structures usually can not be combined with others, that is, the processing of two different plastics gives a macroscopic mixture having insufficient mechanical properties. To improve the compatibility and therefore also the properties of the plastic combinations, so-called compatibilizers are commercially available. These co-catalysts are polymers, which prevent or reduce the separation of -y systems of two or multiple components or that improve dispersion, producing therefore a homogeneous mixture of different plastics with good mechanical properties. Known compatibilizers are based predominantly on polymers of polar and non-polar structures, which are I > produced by customary polymerization reactions- The compatibilizers are used in virgin plastic compositions and also, increasingly, in recycled. In this case, the production process, or the collection of plastics used, often results in plastic compositions, the mechanical properties of which are only suitable for new applications if campaigners are added to them. In Kunststoffe 83 (1993) r 10, 820-822 and in Kunststoffe 85 (1995) 4, 446, 450, K. Hausmann discusses the problem of recycling incompatible plastics, such as polyethylene / polyethylene terephthalate (PE / PET) and polyamide / polyethylene (PA / PE). For recycling, compatibilizers are used. In Kunststo - re 83 (1993) 5, 369-3T2 R.-Grützner, R. Gártner and H.-G. Hock, published research on similar systems (composite sheets of (PE / PA) R. Mühlhaupt and J. Rósch report phase compatibilizers for polypropylene / polyamide alloys (PP / PA) in iC-mststo-T-fe 84 (1994 9) 1153-1158. In -O --- ststo-í? E 83 (1993) 11, 926-929, G. Obieglo y. Romer also describes compatibilizers to be used in plastic recycling. In Recycle, 91, 8 / 5-1 and Recycle 95, 6 / 4-3, S. Fuzessery present compatibilizers and polymeric modifiers for virgin and recycled thermoplastics. It is known how to join stabilizers to a polymer to obtain a better combination in the product to be established and prevent the migration of the stabilizers thereof. This has been suggested, inter alia, by M. Minaga a in Polymer Degradation and Stabili ty 25 (1989), 121-141 or by H. Yamaguchi, M. Itoh, H. Ishikawa and K. Kasuda in J. M. S. -Puré Appl. Chem., A30 (4), (1993), 287-292. In Die Angewandte Makromolekulare Chemie 158/159 (1998), 221-231, in ñdvances in Polymer Science 101, pages 65-167, Springer-Verlag Berlin Heidelberg, 1991 and in Jan Posplsíl, Peter P. Klemchuck, Oxidation Inhibition in Organic Materials , Vol. 1 (1989), 193-224, Jan Pospisil presents a study of "functionalized polymers", ie polymers containing an antioxidant, antiozonant, metal deactivator, photostabilizer or effective biostabilizer EP-A 306 729 describes the union from antioxidants to polymers, the polymers are obtained by reacting a polymer with anhydride functionalities, with an antioxidant with hydrazide functionalities or with a copolymer consisting of N-substituted imides of α, β-unsaturated cyclic dicarboxylic anhydrides (with antioxidant function) and ethylenic or vinyl aromatic monomers The stabilization of plastic compositions against heat and light has a special problem because, depending on the polarity of the components, a non-uniform distribution of the compounds is obtained. stabilizers in the polyphase polymer system (distribution of the stabilizer). This is described, inter alia, in D.M. Kulich, M.D. olko icz and J.C. ozny in Makromol. Chem., Macromol. Symp. 70/71, 407-418 (1993). The distribution balance of the stabilizers is further influenced by the compatibilizers used, which are, moreover, often the least stable component of the composition. The thermal or photo-oxidative damage of the compatibilizers therefore results in a very rapid breakage of the entire composition due to the damage of the compatibilizing component. Accordingly, it is desirable to provide compounds that improve the compatibility of the components in polymer combinations, as well as the mechanical properties and that also ensure protection against oxidative and photooxidative damage. It has now been found that the specific polymers corresponding to the stabilizing side groups possess those properties. Accordingly, this invention relates to a process for establishing and at the same time plastics or plastic compositions that compatibilize the phase by incorporating polymeric compounds obtainable by the reaction of compounds selected from the group consisting of sterically hindered phenols, sterically hindered amines, lactones, sulfides, phosphites, benzotriazoles, benzophenones and 2- (2-hydroxyphenyl) -1,3,5-triazines, compounds which contain at least one functional reactive group, with a compatibilizer.

Typical examples are ethylene / vinyl acetate / maleic anhydride terpolymers, ethylene / ethyl acrylate / maleic anhydride terpolymers, ethylene / acrylic acid / maleic anhydride terpolymers, styrene / maleic anhydride copolymers - or styrene terpolymer / maleic anhydride / methyl methacrylate. Such polymers and their preparation are known and described, inter alia, by PJ Flory in Principles of Polymer Chemistry, 1964, Cornell University Press, Ithaca, NY, as well as in Polymer compatibilizers and modifiers for virgin and recycled thermoplastics, including polymer materials Multiple or multi-layered, Maack Business Services, Study MBS No. 10, September 1990, Zürich. Also preferred as a component of the compatibilizer are copolymers or terpolymers containing a grafted anhydride, such as maleic anhydride grafted to polypropylene, maleic anhydride grafted to polyethylene, maleic anhydride-bonded to ethylene / vinyl acetate copolymer, block copolymer. styrene / ethylene / propylene / styrene (? EPS), styrene / ethylene / butylene / styrene block copolymer (SEBS), maleic anhydride grafted to ethylene / propylene terpolymer (EPDM), maleic anhydride grafted to ethylene / propylene copolymer. Such grafted polymers and their preparation are known and described, inter alia, in H.-G. Elias, Makromoleküle 1981, Hüthing & Wepf Verlag Heidelberg; or -in Polymers and polymer modifiers for virgin and recycled thermoplastics, including multi-polymer or multi-layer materials, Maack Business Services, Study MBS No. 10, September 1990, Zürich; as well as in M. Xanthos, Reactive Extrusion, 1992, Oxford University Press, NY. The maleic anhydride content is typically 0.05-15%, preferably 0.1-10%. Also suitable as a component of the compatibilizer are copolymers or terpolymers containing unsaturated carboxylic acid, typically acrylic acid, methacrylic acid, crotonic acid, fumaric acid, vinylacetic acid, maleic acid, itaconic acid. Acrylic acid, methacrylic acid, fumaric acid and maleic acid are preferred as in acrylic acid and methacrylic acid are particularly preferred. Illustrative examples of such copolymers or terpolymers are the ethylene / acrylic acid copolymer, copolymer of propylene / acrylic acid or terpolymer - ethylene / propylene / acrylic acid. Such polymers and their preparation are described, inter alia, in polymeric modifiers and compatibilizers for virgin and recycled thermoplastics, including multi-polymer and multi-layer materials, Maak Business Services, Study MBS No. 10, September 1990, Ziirich. The content of acrylic acid is typically 0.1-30%, preferably 0.1-25%. The preparation of the polymer, copolymer and terpolymer compatibilizers is carried out with the conventional polymerization processes with which one skilled in the art is familiar. The preparation of the polymers containing a carboxyl group has been published, for example by N.G. Gaylord in 'Reactive Extrusion; Principles and Practice ", Polymer Processing Institute, page 56 et seq., Hanser Verlag, München, Wien, New York (1992) In the same work, p 116 et seq., S. Brown describes the preparation of other carboxylated compatibilizers The reaction of the compatibilizer compound with a compound selected from the group consisting of sterically hindered phenols, sterically hindered amines, lactones, sulfides, phosphites, benzotriazoles, benzophenones and 2- (2-hydroxyphenyl) -1,3,5-triazines, which contain at least one functional reactive group, it is carried out as a graft reaction or analogous polymer reaction. The reactions can be carried out in solution or in the melt, depending on the reactants. Different reactors can be used in this case, for example tanks, extruders, mixers and the like. Extrusion is preferred. Reactive extrusion has been described, inter alia, by M. Xanthos in Reactive Extrusion, Principles and Practice, Polymer Processing Institute, Hanser Verlag, Munchen 1992. The reagents can be fed to the premixed or separated extruder, ie via feed devices separated, and can be reacted in the extruder. Liquid components or low melting point components can also be fed into the extruder via the feed pump (providing side channels). It may also be useful to degas the melt in the extruder, particularly when low molecular weight products are obtained in the reaction, which are preferably removed. For this purpose, the extruder needs to be equipped with a corresponding degassing device. The preparation can be carried out in commercially available single screw or twin screw extruders. The twin screw extruders are preferred. Obtaining the composition is carried out carried out by the usual techniques, for example, granulation. It is also possible to prepare and use a master batch (concentrate) of these compatibilizers / stabilizers by methods known in the art. The ratio of the compatibilizing component to the stabilizing component in the analogous polymeric reactions is, of course, limited by the number of reactive groups present in the compatibilizer components. A suitable weight ratio of compatibilizer / stabilizer is from 100: 0.05 to 100: 50, in particular from 100: 0.1 to 100: 25, preferably from 100: 1 to 100: 20.

The novel compatibilizer / stabilizer compounds are added to the polymer to be stabilized in amounts of 0.5-30%, for example 1-20%, preferably 2-15% (based on the amount of polymer to be stabilized). The quantities depend on the one hand, the number of active stabilizing groups in the compounds and, on the other hand, the requirements of the polymers or polymer combinations to be established. The novel compatibilizer / stabilizer compounds are also used for in-phase compatibilization in plastic compositions where they act as stabilizers at the same time. These plastic compositions can be virgin plastic compositions (as described above) and also recycled. The novel stabilizers / co-stabilizers can, in principle, be used in all incompatible plastic compositions, virgin or recycled materials or in combinations of. virgin material and recycled. The plastic compositions may consist of two or more components. The novel components are preferably added to mixtures of polar and non-polar plastics.
The non-polar components of the plastic composition are, for example, polyolefins, typically polyethylene (PE) and polypropylene (PP). The ones mentioned in particular are low density polyethylene (LDPE), linear low density polyethylene (LLDPE) and high density polyethylene (HDPE), and also copolymers, such as ethylene / propylene copolymers (EPM) and ethylene / propylene / diene (EPDM), as well as ULDPE and MDPE. Such non-polar plastics also include polystyrene (PS, EPS) and copolymers having a styrene component (for example ABS, ASA, HIPS, IPS) and polyvinyl chloride (PVC), as well as copolymers with a vinyl chloride component predominant (for example CPE). The polar components are, for example, polyesters, such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), polyamides or polycarbonates. Mixtures of polyethylene and polypropylene or polyethylene and polyamide are particularly preferred. The novel compatibilizer / stabilizer compounds can be used, for example, in redolated plastic compositions comprising 25-100% by weight, preferably 35-95% by weight, for example 40- 85% by weight of polyolefins, 0-25% by weight of polystyrene, 0-25% by weight of polyvinyl chloride and 0-25% by weight of the other thermoplastics. Non-thermoplastic materials can also be obtained in smaller quantities in the mixture. Of polyolefins, polyethylene (PE), in particular low density polyethylene, usually dominates. It should also be understood that polystyrene (PS) is for copolymers having a predominant styrene component (for example ABS, HIPS), and it should also be understood that polyvinyl chloride (PVC) is for copolymers having a component of predominant vinyl chloride (for example CPE). Other thermoplastics present in the material used are, in particular, polyethylene terephthalate (PET), and also polyamides, polycarbonate, cellulose acetate and polyvinylidene chloride. Thermoplastic materials may also be present in amounts of less than 5%, typically polyurethanes, formaldehyde resins and phenolic resins or also typical aminoplastics, as well as elastomers, such as rubber or latex. Minor amounts of foreign matter may also be present in the plastics used, such as paper, pigments, paint systems, printing inks, adhesives, which are often difficult to remove. Small amounts of cellulose or fibrous materials do not interfere with recycling.
Combinations of the novel compatibilizer / stabilizer compounds can also be added to the plastic compositions to be stabilized and to make them compatible. That is, for example, that it is convenient to use compounds having the same compatibilizing backbone, but which are functionalized differently with respect to the stabilizer, typically mixtures of compounds having a phenolic antioxidant function with compounds having a benzotriazole function, mixtures of compounds that have an antioxidant function with compounds having a HALS function, mixtures of compounds having a HALS function with compounds having a UV-absorbing function or, for example, mixtures of compounds having an antioxidant function with compounds having a HALS function and with compounds that have a UV absorbing function. The plastic compositions can be further mixed with other additives known to those skilled in the art. These additional additives are used in the usual quantities and combinations, detailed in the relevant literature (for example "Plastic Additives", Gachter / Müller, Hanser Verlag, München / Wien / New York, 3rd edition). The incorporation of novel compatibilizers / stabilizers into polymers or polymer combinations to be stabilized can be conveniently carried out as follows: as emulsion or dispersion; - as a dry mixture while combining the additional components or polymer combinations; by direct addition to the processor apparatus (for example calender, mixer, - kneader, extruder and the like), or - as a solution or in a molten state. The plastic compositions can be prepared in a manner known per se, by mixing the novel compounds and additional optional additives with the plastic composition, using the apparatuses known per se, such as the aforementioned processing apparatuses. The additional additives can be added alone or in mixture or also in the form of so-called master batches. By adding a suitable monomeric functionalized stabilizing compound and a radical initiator to the plastic composition directly, while processing the mixture, i.e. without a prior separate preparation of the compatibilizer / stabilizer compound, it is more possible to produce the compatibilizer / stabilizer compound and the composition compatible plastic in one step of the process. Similarly, it is possible to process a compound monomeric functionalized stabilizer - suitable and a corresponding compatibilizer together with the polymer blend, so that the compatibilizer compound reacts with a stabilizer compound without prior processing, and improve the compatibilized polymer blend obtained at the same time. The plastic compositions obtained according to this invention can be brought to the desired shape in a known manner. Such processes are, for example, grinding, calendering, extrusion, injection molding, sintering or centrifugation, and also blow molding by extrusion or processing by the plastisol process. The novel process comprises two different aspects, that is to say that two main purposes are achieved using the novel polymeric compatibilizer / stabilizer compounds. On the one hand, the polymers become compatible with each other in combinations of different polymers (virgin or recycled material), which, without compatibilizers, would form several phases, and the polymer is stabilized at the same time. On the other hand, the stabilizer becomes compatible or its solubility in the polymer increases because the polymeric backbone of the compatibilizer / stabilizer compound is compatible with the polymer to be stabilized. This also reduces the migration of the polymer stabilizer, which it is conceivable, for example, in the extraction of environmental media. This is the case, for example, when the compounds are used for fuel tanks, geotextiles, dry cleaning fibers (for example, textiles, carpet floors), pipes, applications with contact with food products and the like. The following Examples illustrate the invention in more detail. Here, as well as in the remainder of the description and in the claims, the parts and percentages are by weight, unless otherwise indicated.
I. Preparation of functionalized polymers Example A In a twin screw extruder (TW 100, from Haake, Germany), a copolymer of SEBS (styrene / ethylene / butadiene / styrene copolymer) was extruded with maleic anhydride groups (KratonßFG 1901, from Shell) at a temperature of 210-230 ° C (heating zone 1-5) and 45 rpm, with the addition of 2% of 3,5-bis (1,1-dimethylethyl) -4-hydroxybenzenepropionate 2,3-epoxypropyl. Subsequent analysis by gas chromatography shows that the additive can no longer be detected in its original form, that is, it is completely bound to the polymer chain.
Example B In general analogy with Example A, a polyethylene / acrylic acid / acrylate (Lucalen * A 3110 MX, ex BASF) was extruded with 2% of 3,5-bis (1,1-dimethylethyl) -4-hydroxy- 2,3-epoxypropyl benzene propionate.
Example C The procedure of Example B was repeated, but using 4% of 3,5-bis (1,1-dimethylethyl) -4-hydroxybenzene propionate of 2,3-epoxypropyl, Example D In general analogy with Example A, a? EB? Copolymer was reacted. with groups of maleic anhydride with 2% of 1, 2, 2, 6, 6-pehtamethyl-4- (2,3-epoxypropyloxy) -piperidine.
Example E In general analogy with Example B, it was reacted -polyethylene / acrylic acid / acrylate with 2% of 1, 2, 2, 6, 6-pentamethyl-4- (2,3-epoxypropyl) -piperidine.
Examples F, G, H In general analogy with Example E, 4%, 6% and 8% of each of 1, 2, 2, 6, 6-pentamethyl-4- (2,3-epoxypropyloxy) iperidine were used .
II) Use of polymeric stabilizers Examples 1-3 (Impact resistance as a function of oven aging) A composite mixture of 70% LDPE, low density polyethylene was added to the test products obtained.
(Lupolen® 3026, from BASF) with polyamide 6 (Ultramid® B 30, preseca, from BASF) with the functionalized compatibilizers prepared in the above Examples at 240 ° C and at 75 rpm (double screw extruder TX 100, Haake, Germany), were granulated and then injection molded at 240 ° C to the test samples. The impact resistance of these test samples was determined according to DIN 53 448, as a function of aging at 100 ° C in a circulating air oven. For comparison purposes, compositions were prepared and tested which comprised the corresponding non-functionalized compounds instead of the functionalized compatibilizers. The test compositions and the test results are given in the following Table 1. The higher the value of the impact resistance, the more stable the composition tested.
Table 1 The values obtained show that the functionalized compatibilizers stabilize the polymer more effectively when they are aged for a longer period of time than non-functionalized compatibilizers.
Examples 4-8: (Resistance to impact as a function of artificial environmental conditions) In general analogy with the method described in Examples 1-3, test samples were prepared and their impact resistance was determined as a function of the conditions artificial environmental The environmental conditions were carried out in an environmental meter O [Type Ci 65A, Atlas, BPT (black panel temperature) 63 ° C, RH (relative humidity) 60%, water spray]. The compositions and test results are shown in Table 2.
Table 2 The values obtained from the functionalized compatibilizers stabilize the polymer more effectively when maintained at ambient conditions for a prolonged period of time than non-functionalized compatibilizers. - - _ Examples 9-12: (impact resistance as a function of oven aging after extraction) A mixture of 70% low density polyethylene (LDPE) (Lupolenf3026 F, from BASF) with 30% polyamide 6 (Ultramid® B36 , preseca, from BASF) was composed with the novel compatibilizers / stabilizers compounds to be tested at 240 ° C and at 75 rpm, in a twin screw extruder. The test samples were then injection molded at 240 ° C. Those test samples were stored in an extraction medium: A) in white spirit - for 25 days at room temperature, B) in water with 1% Igepal CO630 (nonoxynol 9) for 2 weeks at 40 ° C. The dried test samples were then aged at 100 ° C in an oven with air circulation. The impact resistance was determined according to DIN 53 448 as a function of aging. The higher the value of impact resistance and the smaller decrease in this value after aging, the more stable the composition tested. The compounds tested and the test results for the extraction variant A are given in Table 3 and for those of variant B are given in Table 4. Table 3 Table 4
