Abstract

PURPOSE: The polymerization is effected by adding a heated aqueous medium to a uniform mixture system of vinyl chloride monomer and the polymerization initiator to shorten the polymerization time sharply and produce a high-quality vinyl chloride polymer with less fish eyes.
CONSTITUTION: Vinyl chloride monomer and a polymerization initiator such as di-2-ethylhexyl peroxycarbonate are charged in a polymerizer and stirred to form a uniform mixture. Then, a heated aqueous medium such as a solution containing partially saponified polyvinyl alcohol is added to the mixture to initiate the polymerization reaction and the polymerization is effected as the reaction heat is removed. The aqueous medium is preferably heated to such a temperature as the polymerization system becomes -5≤T≤2 to the polymerization temperature (T°C), when it is added to the polymerizer.
