摘要： In a substantially isothermal process for the polymerization of vinyl halide monomer formulations in aqueous dispersion, the desired polymerization temperature is maintained by heat-exchange contact with the liquid phase, by condensation and return of vapors and by injection of a relatively low temperature inert liquid. Stable dispersion for the suspension/reflux polymerization temperature may be enhanced by use of a mixture of a cellulose ether, a partially hydrolyzed polyvinyl acetate and a sorbitan fatty acid ester.

THE UNIFORMITY OF THE PRODUCT BEADS CAN BE FURTHER IMPROVED BY USING AS THE DISPERSING AGENT A PARTIALLY SAPONIFIED VINYL ACETATE-DODECYLVINYL ETHER COPOLYMER.
