ABSTRACT OF DISCLOSURE A polymer scale preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising a condensation product of: (A) an aromatic amine compound, and (B) an aromatic hydroxyl compound condensate. This agent is used for forming a coating on the inner wall, etc. of a polymerization vessel. Such a vessel is effective in preventing polymer scale deposition and use- ful in producing a polymer that shows very few fish eyes and good whiteness when formed into sheets or the like.
