ABSTRACT:
The impact resistance of resin compositions consisting of a thermoplastic polymer, particularly a homopolymer or copolymer of vinyl chloride, can be improved by an impact additive of the graft copolymer type. The graft copolymer impact additive consists of a backbone composed of a statistical copolymer of butadiene or isoprene, an alkyl acrylate of a C.sub.2 to C.sub.12 alkyl, and a polyfunctional cross-linking agent, onto which are grafted the chains of a polymer of an alkyl methacrylate of a C.sub.1 to C.sub.4 alkyl, particularly methyl methacrylate. The backbone of the graft copolymer impact additive comprises 0.5-35% by weight butadiene or isoprene, and up to 10 mole % of the cross-linking agent, while the weight ratio of grafted chains to the backbone can range from 10 to 200%.
The resin compositions are particularly useful to improve impact strength at low temperatures.
