ABSTRACT:
A polymer scale preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising an alkaline solution containing a condensation product of (A) an aliphatic diamine compound and (B) an aromatic tetracarboxylic acid anhydride. 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, not only on the areas in the liquid phase but also near the interface between the liquid phase and the gas phase in the vessel, and useful in producing a polymer that shows very few fish eyes and good whiteness when formed into sheets or the like.
