Method of preventing polymer scale deposition and polymer scale preventive agent. |
摘要 |
<p>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) a water-soluble nitrogen-containing cationic polymeric compound, and (B) a water-soluble anionic polymeric compound; and a polymer scale preventive agent comprising said (A) and (B). Polymer scale deposition is effectively prevented, and polymers with high whiteness can be prepared. v</p> |
