Abstract
The invention relates to notched impact resistant thermoplastic moulding compositions obtained from 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 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.
Claims2
A notched impact resistant thermoplastic moulding composition of
- (I) 1.0 to 99% by weight of a thermoplastic vinyl chloride polymer, and
- (II) 99 to 1.0% by weight of a particulate graft polymer consisting of a core (a) of a highly cross-linked diene rubber, a first covering (b) of a cross-linked acrylate rubber, and a second covering (c) of a polymer or copolymer of at least one resin-forming monomer selected from the group consisting of styrene, .alpha.-methylstyrene, acrylonitrile, methacrylonitrile, acrylic acid esters and methacrylic acid esters.
