摘要
Process for the polymerization of vinyl chloride in aqueous suspension in the presence of a dispersing system comprising a cellulosic derivative and an anionic emulsifying agent wherein the polymerizaton is initiated by an oil-soluble initiator and a water-soluble free radical polymerization initiator is added in the course of polymerization. The thus obtained polyvinyl chloride powders are particularly suitable for the production of battery separators.
