Abstract

1348426 Polymerizing vinyl chloride BADISCHE ANILIN- & SODA-FABRIK AG 23 July 1971 [25 July 1970] 34596/71 Heading C3P A batch process for the suspension polymerization of vinyl chloride is effected by initially charging 10-80% of the vinyl chloride to the polymerization, after 10-60% of this initial charge has polymerized adding further vinyl chloride in the liquid phase, stopping addition before conversion exceeds 70% of the total vinyl chloride introduced and continuing polymerization until at least 85% conversion is achieved. Preferably the liquid vinyl chloride is added continuously into the gas phase of the reactor. The product shows a narrow particle size range and articles made from it have few fish eyes. The protective colloid is preferably a mixture of a cellulose ether and polyvinyl alcohol.
