Abstract:
A vinyl chloride resin composition comprising a vinyl chloride resin and 0.1 to 30 parts by weight of a processing aid per 100 parts by weight of said vinyl chloride resin,wherein said processing aid is a polymer prepared by polymerizing (B) 70 to 97 parts by weight of a monomer mixture comprising 60 to 100% by weight of methyl methacrylate, 0 to 40% by weight of at least one monomer selected from the group consisting of an alkyl acrylate and an alkyl methacrylate different from methyl methacrylate and 0 to 10% by weight of other vinyl monomer copolymerizable therewith, in the presence of a latex prepared by emulsion-polymerizing (A) 3 to 30 parts by weight of a monomer mixture comprising 0 to 45% by weight of methyl methacrylate, 55 to 100% by weight of an alkyl acrylate and 0 to 20% by weight of other vinyl monomer copolymerizable therewith, the total amount of said mixtures (A) and (B) being 100 parts by weight, and said polymer has a specific viscosity of at least 1 measured at 30.degree. C. with respect to a solution of 0.4 g of said polymer in 100 ml of benzene.
