Abstract: A film-forming composition comprises from 0.1-8% by weight of an oligomeric polyglycidyl ether or ester and a polymer mixture ofa) a graft polymer prepared by polymerizing a monomer mixture of acrylonitrile, and alpha-methylstyrene and/or an alkylmethacrylate; or methylmethacrylate optionally with other monomers, onto cross-linked alkylacrylate rubber particles;b) a partially cross-linked rubber-like copolymer derived from an alkylacrylate and other monomers;c) an uncross-linked polymer of styrenes, (meth)acrylonitrile, (meth)acrylic acid esters and/or vinyl carboxylic acids; and optionallyd) a graft polymer obtained from the polymerization of a mixture of acrylonitrile, and styrenes and/or an alkylmethacrylate; or methylmethacrylate optionally with other monomers, onto cross-linked alkylacrylate rubber particles.

Abstract: This invention relates to soft, rubber-like, thermoplastically processible polymer alloys based on 10 to 50% by weight of (cyclo)aliphatic, thermoplastic polyamides and 90 to 50% by weight of special cross-linked, particulate alkyl acrylate copolymer rubbers suitable for the preparation of rubber-like, elastic moulding compounds.The invention also relates to a process for their preparation.

Abstract: Polymer mixtures having high tensile strength and good tear propagation resistance, consisting of(A) from 10 to 95 parts by weight of a graft polymer,(B) from 0 to 75 parts by weight of a thermoplastic resin component and(C) from 5 to 60 parts by weight of a copolymer having a sequence type of structure corresponding to the idealized formula (I)(A--X--B).sub.n (I)whereinA=polymer of a cyclic carbonate,B=polymer of another cyclic ester andX=middle member containing partial structures of both A and B.

Abstract: Fogging of plastics containing polymer plasticizers is reduced by treating the polymer plasticizers with water vapor in the melt.

Abstract: Soft polymer mixtures of(a) 10 to 50 parts by weight of a graft polymer obtained from a particulate, highly cross linked diene or alkyl acrylate rubber and graft polymerized alkyl methacylate, acrylonitrile, styrene, alkyl acrylate or mixtures thereof and(b) 90 to 50 parts by weight of a partly cross-linked, particulate, rubber-like copolymer of acrylonitrile and/or methyl methacrylate and C.sub.1 to C.sub.8 alkyl acrylate having a gel content of from 60 to 99% by weight and an average particle diameter (d.sub.50) of from 0.1 to 0.6 .mu.m,and a process for the preparation of the mixtures and their use for the production of moulded articles.

Abstract: The object of the invention is the use of ethylene-vinyl acetate-copolymers produced by emulsion polymerization and containing unipolymerized acids, for the modification of polyvinyl chloride.

Abstract: A notched-impact-resistant polyvinyl chloride moulding composition having a low shrinkage value, based on vinylchloride polymers and impact-resistant modifiers, containing from 0.01 to 5% by weight, based on the total of vinylchloride polymer and impact-resistant modifier, of liquid polysiloxanes having viscosities of from 20 to 100,000 cSt and/or solid polysiloxanes having molecular weights of from 20,000 to 500,000 and optionally conventional additives and auxiliaries.
