摘要： A method of preventing polymer scale formation in a polymerization vessel during the polymerization of a monomer having an ethylenically double bond, wherein said polymerization is carried out in a polymerization vessel in which its inner wall surface has been previously coated with a coating solution containing (A) at least one member selected from the group consisting of particular anionic dyes, and alkali metal salts and ammonium salts of a sulfonated product obtained by sulfonation of a condensate of a particular aromatic amine compound with a particular aromatic nitro compound, and (B) a particular cationic dye and having a pH of more than 7, and then dried to form a coating. This method can effectively prevent scale formation in the polymerization of extensive monomers having an ethylenically double bond, so that 100 or more polymerization runs can be repeated without formation of polymer scale.
