Abstract

PURPOSE: To prevent deposition of polymer scales, by previously applying an aqueous solution containing an anionic high-molecular compound and a metal salt to the monomer contact areas of a polymerization vessel, such as inner surfaces, and drying the applied solution, in the polymerization of vinyl monomers in an aqueous medium.
CONSTITUTION: An aqueous solution prepared by dissolving in water (i) a water- soluble anionic high-molecular compound such as sulfomethylated polyacrylamide, (ii) a water-soluble metal salt such as CaCl2 and, optionally, (iii) a monohydric C3W6 alcohol such as n-propyl alcohol is applied to the monomer contact areas, such as inner walls, agitator blades and an agitator shaft, of a stainless or glass- lined polymerization vessel, and the applied solution is dried. Next, into this coated polymerization vessel are charged water, a vinyl monomer such as vinyl chloride, a polymerization initiator and other additives. Then, the mixture is subjected to suspension or emulsion polymerization.
