Abstract

PURPOSE:To prepare an aqueous dispersion of a copolymer having excellent heat flowability and strength, by adding a specific amount of a polyallyl ester of a polybasic acid to vinyl chloride and a vinyl ester, feeding the mixture continuously to an aqueous polymerization system under ethylene pressure, and carrying out emulsion polymerization. CONSTITUTION:In the copolymerization of (A) vinyl chloride, (B) a vinyl ester and (C) thylene in an aqueous solvent, the polymerization system is fed with (D) 0.1-1.0wt%, based on (A)+(B), of a polyallyl ester of a polybasic acid expressed by the formula (X1-X4 are allyl ester group or one of them is H), continuously, under ethylene pressure, in the presence of an emulsifier and a radical polymerization initiator. More than 60wt% of the component (A) and (B) are continuously added to the polymerization system, and a copolymer consisting of 20-75wt% of (A), 15-70wt% of (B) and 5-30wt% of (C) and containing 5-60wt% of the fraction insoluble in benzene, is obtained.
