ABSTRACT:
Polymerization of vinyl chloride monomer, by either suspension or emulsion polymerization, optionally in the presence of a monoethylenically unsaturated comonomer, is carried out in the presence of a mixture of calcium and zinc acrylate. The presence of the calcium and zinc acrylate yields a more thermally stable product and reduces the amount of polymer scale formation during polymerization. A further improvement in thermal stability is achieved by conducting the polymerization with the added presence of an epoxy compound containing a reactive vinyl or allyl group.
