    摘要: A: Thermoplastic moulding materials made from a vinyl chloride homopolymer or copolymer containing at least 50% by weight of vinyl choloride units,B: a graft polymer, prepared by graft polymerization ofB1: 50 to 85 parts by weight of a mixture of at least two of the monomers styrene, acrylonitrile, methyl methacrylate and .alpha.-methyl styrene onB2: 50 to 15 parts by weight of an at least partially crosslinked butadiene or acrylate rubber having average particle diameters of 0.08 to 1 .mu.m, andC: a hydrogenated nitrile rubber in which the nitrile group content is 50 to 28% by weight and the degree of hydrogenation is greater than 50%, andD: optionally, a non-crosslinked, rubber-like ethylene or alkyl acrylate polymer, optionally containing copolymerized up to 70% by weight of vinyl acetate, acrylonitrile, methyl methacrylate or carbon monoxide,E: optionally at least partially crosslinked, rubber-like ethylene or alkyl acrylate polymer, optionally containing copolymerized up to 50% by weight of vinyl acetate, acrylonitrile, methyl methacrylate or carbon monoxide.
