Vinyl chloride resin composition

Abstract

Abstract PURPOSE: Title composition that is composed of a vinyl chloride resin and a specific aid, thus having good processability and showing high mechanical properties. CONSTITUTION: To (A) 100 parts by wt. of a vinyl chloride resin containing more than 80wt% of vinyl chloride are added (B) 0.1W30 parts of a processing aid that consists of (a) 40W90 parts of a polymer blend from 80W100wt% of alkyl methacrylate and 0W20wt% of one or more kinds of vinyl monomers copolymerizable with the alkylate and (b) 60W10 parts of another copolymer from 20W79wt% of an aromatic vinyl monomer, or 20W79wt% of dialkyl itaconate or alkyl acrylate, 1W49wt% of a diolefin, and 0W20wt% of monomers copolymerizable with them or a compolymer obtained by polymerization of monomers for forming one copolymer in the presence of the other copolymer.
