Process for the polymerization of vinyl chloride |
| abstract |
Abstract of the Disclosure Polymerizatlon of vinyl chloride monomer, by either sus-pension 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 yield 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. |
