Abstract

PURPOSE: To improve the productivity and quality of polymer, by increasing the quantity of heat removed in a condenser with the progress of reaction, in suspension-polymerizing vinyl chloride type monomers in a polymerization vessel equipped with a cooling jacket and a condenser.
CONSTITUTION: In suspension-polymerizing vinyl chloride type monomers, e.g., a mixture of vinyl chloride with vinyl acetate or styrene, by use of a dispersing aid, e.g., methylcellulose, and a polymerization initiator in a polymerization vessel equipped with a stirrer and a jacket and condenser for heat removal; during a period from the start of the polymerization to a point at which the monomer conversion reaches 5%, the quantity of heat removed in the condenser is controlled to below 35% of the quantity of heat generated by the polymerization. Then,the polymerization is accomplished by increasing the quantity of heat removed in the condenser so that at least at the peak of heat generation, 50W90% of the quantity of heat generated by polymerization can be removed. This lakes it possible to perform high-speed polymerization in a large polymerization vessel and thereby to shorten the reaction time.
