High impact ternary blend PVC moulding compositions

摘要

Thermoplastic moulding compositions ofPPA. 65 to 95% by weight polyvinyl chloride or vinyl chloride copolymer having K- values of 50 to 80,PPB. 2 to 25% by weight of a chlorinated polyolefin or of a chlorinated olefin copolymer with a chlorine content of 20 to 80% by weight,PPC. 3 to 30% by weight of a graft polymer produced by grafting styrene or styrene and acrylonitrile and optionally copolymerizable monomers onto an EPDM rubber as graft base.
