Polymer scale preventive agent, polymerization vessel for preventing
polymer scale deposition, and process of producing polymer using said
vessel
摘要:
A polymer scale preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising a pyrogallol-acetone resin. The agent is used for forming a coating on the inner wall, etc. of a polymerization vessel. Deposition of polymer scale can be effectively prevented, and polymeric product with high whiteness is obtained.
