  A method of preventing polymer scales from sticking 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 of which the inner wall and other parts with which said monomer comes into contact during polymerization are previously first coated with (a) a coating solution comprising a cationic dye and the resulting coating is then coated with (b) a coating solution comprising at least one component selected from the group consisting of anionic polymeric compounds, amphoteric polymeric compounds and hydroxyl group-containing organic compounds. Polymer scale formation can be effectively prevented.

  一种在具有乙烯双键的单体聚合过程中防止聚合物鳞片粘附在聚合容器中的方法，其中所述聚合在聚合容器中进行，聚合容器的内壁和在聚合过程中与所述单体接触的其他部分之前先涂有(a)由阳离子染料组成的涂层溶液，然后在所得涂层上涂有(b)由至少一种从阴离子聚合物化合物、两性聚合物化合物和含羟基有机化合物组成的组中选出的组分组成的涂层溶液。可有效防止聚合物结垢。
