Abstract

PURPOSE: The temperature of the reflux condenser in the polymerizer is set to specific degrees on the initiation and during the polymerization to prevent the scale deposition on the condenser and other equipment and enable continuous production in an industrial production scale.
CONSTITUTION: Vinyl chloride or a mixture thereof with other monomers copolymerizable is subjected to suspension polmerization in an aqueous medium in a polymerizer equipped with a reflux condenser using at least one of cellulosic derivatives and partially saponified polyvinyl alcohol as an initator, whererein the reflux condenser is heated higher than the polymerization temperature, when the polymerization is initiated and the temperature is kept until the polymerization suspension reaches the prescribed temperature. After that, the reflux condenser is kept more than 15°C lower than the polymerization temperature.
