Abstract

PURPOSE: To enable the increase in feed amount of polymerization, by regulating the feed amounts of cooling water, hot water, and steam to a condenser while raising the polymerization temperature gradually after the middle stage of polymerization, carrying out suspension polymerization for vinyl chloride resin with suppressing foaming.
CONSTITUTION: A polymerizer is charged with pure water, a polymerization initiator (e.g., lauroyl peroxide), a dispersant (e.g., partially saponified polyvinyl alcohol), and vinyl chloride or a vinyl monomer (e.g., ethylene) mixture consisting essentially of it. Cooling water and hot water or steam are used in the cooling water side of a condenser attached to the polymerizer, the polymerization is started while regulating the cooling water and hot water or steam and controlling the foaming in the polymerizer, and the polymerization temperature after the middle stage of the polymerization is raised gradually, to give the desired vinyl chloride resin.
EFFECT: The polymerization conversion can be raised to improve productivity, and the saving of steam for heating is made possible.
