ABSTRACT:
A method of preventing polymer scale deposition during polymerization of a monomer having an ethylenically double bond in a polymerization vessel, comprising the step of carrying out said polymerization in a polymerization vessel of which the inner wall surface has a coating comprising a water-soluble polysaccharide; and a polymer scale preventive agent comprising polysaccharide. By use of the method or agent, deposition of polymer scale can be effectively prevented; in addition, polymers with a high whiteness can be prepared. Moreover, the scale preventive agent used has no poisonousness or the like and is highly safe.
