ABSTRACT:
This invention relates to a halogen-containing thermoplastic resin composition comprising 100 parts by weight of a halogen-containing termoplastic resin (A) and 1 to 100 parts by weight of a graft polymer (B) having a melt index of 1 to 15 g/10 min as determined at a temperature of 190.degree. C. under a load of 2.16 kg and a benzene-insoluble fraction content of not more than 30 percent by weight as obtainable by graft-polymerizing 100 parts by weight of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 50 to 90 percent by weight as a substrate with 5 to 50 parts by weight of at least one monomer which, when polymerized alone, gives a homopolymer with a glass transition temperature of 65.degree. to 150.degree. C. (b2). This resin composition has markedly improved long-run moldability.
