摘要： Thermoplastic resinous compositions consisting essentially of a blend of (1) 10 to 70% by weight of a chlorinated vinyl chloride resin having a chlorine content of 61 to 70% and specific viscosity ( Eta SP) being 0.18 to 0.35, and (2) 90 to 30% by weight of a resin blend consisting essentially of (A) 80 to 40% by weight of a resin copolymer consisting essentially of 30 to 80% by weight of alpha methyl styrene, 5 to 50% by weight of methyl methacrylate, and 3 to 30% by weight of acrylonitrile; and (B) 20 to 60% by weight of a graft copolymer consisting essentially of 65 to 35% by weight butadiene homopolymer or copolymer containing more than 50% of butadiene copolymerizable with other monoolefinic monomers and 35 to 65% by weight of monomers of 25 to 80% by weight of styrne, 10 to 75% by weight of methyl methacrylate and 0 to 25% by weight of acrylonitrile.
