Abstract

PURPOSE: To prevent sticking of scales, in the polymerization of a vinyl monomer in an aqueous medium, by polymerizing the vinyl polymer in a polymerizer, which is coated with an aqueous solution containing a water-soluble anionic dye, a water- soluble cationic dye and an amine compound.
CONSTITUTION: In the polymerization of a vinyl monomer in an aqueous medium, the inside wall of the polymerizer and the other parts, with which the monomer comes into contact, are previously coated with an aqueous solution containing (A) a water-soluble anionic dye, (B) a water-soluble cationic dye and (C) a 1W6C secondary amine compound, and dried. The secondary or tertiary amine compound is diethylamine methylbutylamine, methylethylpropylamine, methyldipropylamine, etc.
