Abstract
The invention relates to notched impact resistant thermoplastic moulding compositions obtained from PA1 1. 1 to 99% by weight, preferably 10 to 95% by weight, especially 70 to 98% by weight, of a thermoplastic vinyl chloride polymer, and PA1 2. 99 to 1% by weight, preferably 90 to 5% by weight, especially 2 to 30% by weight, or a particulate graft copolymer consisting of a nucleus (a) of a highly crosslinked diene rubber, a first covering (b) of a crosslinked acrylate rubber, and a second covering (c) of a polymer or copolymer of resin-forming monomers, viz. Styrene, .alpha.-methylstyrene, acrylonitrile, methacrylonitrile, acrylic acid esters and methacrylic acid esters.
