Claims
- 1. A thermoplastic moulding composition comprising
- (a) 75 to 99 parts by weight of a graft polymer of 90 to 99% of vinyl chloride onto 1 to 10% by weight of an ethylene vinyl ester copolymer, and
- (c) 1 to 25 parts by weight of a graft polymer consisting essentially of ethylene propylene terpolymer rubber onto which is grafted a member selected from the group consisting of styrene, methylmethacrylate, a mixture of styrene and methlymethacrylate, and a mixture of styrene and acrylonitrile.
- 2. A moulding composition as claimed in claim 1, wherein the ethylene vinyl ester copolymer is an ethylene vinyl acetate copolymer with a vinyl acetate content of from 20 to 80% by weight.
- 3. A moulding composition as claimed in claim 2, wherein the ethylene vinyl acetate copolymer has a vinyl acetate content of from 25 to 55% by weight.
- 4. A moulding composition as claimed in claim 1, wherein the graft base of component (b) contains 1 to 15 carbon-carbon double bonds per 1000 carbon atoms.
- 5. A moulding composition as claimed in claim 1, wherein the ethylene-propylene terpolymer constitutes at most 18% by weight of the total composition.
