Abstract

PURPOSE: To obtain a polyvinyl chloride having a dense particle structure with improved porosity and excellent gelation properties, by adding a specific modified polyvinyl alcohol and a cellulose derivative as suspension stabilizers to the polymerization system.
CONSTITUTION: (B) A modified polyvinyl alcohol having an auerage polymerization degree of 300W2,500 and a saponification degree of 65W80mol% to give a cloud point of 4wt% aqueous solution of 60°C or above and (C) a cellulose derivative, e.g. hydroxypropyl methyl cellulose to give a viscosity of 2wt% solution (20°C) of 500 cps or less as suspension stabilizirs are added to (A) vinyl chloride monomer simultaneously to effect the suspension polymerization.
