Abstract
A vinyl chloride resin composition consisting essentially of a vinyl chloride polymer or copolymer of 70% or more by weight vinyl chloride and 30% or less by weight of one or more monomers copolymerizable therewith and a graft copolymer prepared by graft copolymerizing one or more monomers selected from alkyl methacrylate, vinyl aromatic compound and unsaturated nitrile, in the presence of an aqueous dispersion of alkyl acrylate elastomer obtained by copolymerizing an allyl ester of vinyl or vinylidene unsaturated alpha-carboxylic acid and alkyl acrylate.
