Abstract
A suspending agent system, a polymerizable reaction mixture, and a polymerization reaction process for producing high bulk density resin on a consistent basis by incorporating in the reaction mixture prior to initiation of the reaction about 1-250 parts per million by weight of polymerization inhibitor and also including about 0.001-0.1 parts by weight based on the weight of VCM of a highly hydrolyzed PVA. Preferred PVA's have a 4 weight percent aqueous solution viscosity of 30-100 centipoise and an effective polymerization inhibitor is diethylhydroxylamine. Bulk densities may be increased from about 3-10% depending upon the size of the reaction and the particular ingredients chosen.
