Abstract
PURPOSE: To obtain a polymer having little fish eye with increased operating efficiency of a polymerizer, by mixing and polymerizing a vinyl chloride monomer in a heated aqueous medium in the presence of a suspension agent and a polymerization inhibitor.
CONSTITUTION: Vinyl chloride or a vinyl monomer mixture, primarily composed of vinyl chloride, is mixed with a preheated aqueous medium and suspension- polymerized with addition of a polymerization initiator, in the presence of a suspension agent and a polymerization inhibitor. The temperature of the aqueous medium is preferably about 40W70°C. A temperature ≤40°C has little effect on reducing the time, required for temperature rise after all components are fed, but a temperature ≥70°C makes the feeding of the vinyl chloride monomer in the first step, difficult. The suspension agent is a saponified polyvinyl alcohol, methylcellulose, etc. The polymerization inhibitor is 2,2-di-(4'-hydroxyphenyl)propane, hydroquinone, etc.
