ABSTRACT:
A transparent vinyl chloride resin composition excellent in surface gloss and resistant to weathering and impact, comprising 97 to 60 parts by weight of a vinyl-chloride polymer and 3 to 40 parts by weight of a graft copolymer (B) obtained by emulsion-polymerizing a mixture of an aromatic vinyl monomer and a polyfunctional crosslinking agent having at least one allyl group, then polymerizing, in the presence of the resulting polymer latex, a mixture of an alkyl acrylate having 2 to 10 carbon atoms in the alkyl group and a polyfunctional crosslinking agent having at least one allyl group to form an acrylic elastomer (A) in the first stage the proportions of said alkyl acrylate and said aromatic vinyl monomer being 50 to 70% by weight and 50 to 30% by weight, respectively, and the amount of said crosslinking agent used being 0.1 to 5 parts by weight in total per 100 parts by weight of the sum of said alkyl acrylate and said aromatic vinyl monomer; and graft-polymerizing, in the presence of the resulting acrylic elastomer (A), first methyl methacrylate and subsequently an aromatic vinyl monomer in the second stage, the proportions of said methyl methacrylate and said aromatic vinyl monomer being 30 to 80% by weight and 70 to 20% by weight, respectively, and the total amount of said methyl methacrylate and said aromatic vinyl monomer used being 70 to 20 parts by weight per 30 to 80 parts by weight of said acrylic elastomer (A).
