Abstract
A vinyl chloride polymer composition comprising (A) 5 to 50% by weight of a MBS resin prepared by firstly graft-polymerizing 15 to 40 parts by weight of monomer component comprising 80 to 100% by weight of methyl methacrylate and 20 to 0% by weight of one or more other vinyl monomers capable of copolymerizing with methyl methacrylate onto 40 to 70 parts by weight of a styrene-butadiene rubber including not more than 50% by weight of styrene, and then, onto the obtained copolymer, secondly graft-polymerizing 10 to 40 parts by weight of monomer component comprising 80 to 100% by weight of styrene and 20 to 0% by weight of one or other vinyl monomers capable of copolymerizing with styrene, a total amount of said styrene-butadiene rubber, the first graft-polymerizing monomer component and the second graft-polymerizing monomer component being 100 parts by weight, and (B) 95 to 50% by weight of vinyl chloride polymer wherein;
