ABSTRACT:
A copolymer comprising (a) vinyl chloride or a mixture of vinyl chloride and a monomer copolymerizable therewith and (b) 1,2-polybutadiene oligomer and/or epoxidized 1,2-polybutadiene oligomer. The plasticized copolymer can be molded into soft moldings having a low compression set and high tensile and tear strengths. Also, by the incorporation of the copolymer into vinyl chloride homopolymer or copolymers, hard moldings having delustered surface can be obtained without conducting delustering operation.
