摘要

A process of preparing polyvinyl chloride by the polymerization of monomeric material consisting essentially of vinyl chloride in an aqueous medium containing a suspension vehicle, catalyst for the polymerization, and at least one additive such as stabilizers, lubricants, fillers and pigments. Free-flowing polyvinyl chloride is obtained by dissolving ethylene-vinyl ester copolymer in the vinyl chloride before beginning the polymerization.
