Abstract

PURPOSE: To prevent deposition of polymer scale to a polymerization apparatus, by adding a tin compound, an organic hydroxycarboxylic acid (salt) and a specific initiator to the polymerization system.
CONSTITUTION: Vinyl chloride or a vinyl monomer mixture containing vinyl chloride is polymerized in an aqueous medium in the presence of pref. 0.5W200ppm, based on the monomer, of a tin compound (e.g. stannous chloride) and pref. 5W 2,000ppm of an organic hydroxycarboxylic acid (salt) (e.g. citric acid.), and acetylcyclohexylsulfonyl peroxide initiator or its mixture with other initiators. If desired, the tin compound and the organic hydroxycarboxylic acid (salt) are preliminarily coated onto the surface which contacts with the monomer during polymerization.
