Abstract
A suspension polymerization process of vinyl chloride monomer, alone or in mixture with other copolymerizable monomers, characterized in that the polymerization reaction is carried out in the presence of poly (vinyl acetate) having a number average molecular weight between 10,000 and 30,000, and which is partially hydrolyzed so that its saponification index is between 300 and 500.
