| Abstract: | Emulsion polymerization at low temperature is speedy and effective for synthesis of high molecular weight poly-vinylalcohol. Polyvinylacetate are polymerized by emulsion polymerization at low temperature with oxidation - reduction initiator and mixed emulsors. Two types of oxidation - reduction initiator are compared. The effects of temperature on polymerization rate and the degree of polymerization of polyvinylalcohol are studied. The relation between conversion and degree of polymerization is discussed. |
