Polymer scale deposition preventive agent |
摘要 |
Provided is a polymer scale deposition-preventive agent. It includes (A) a condensation reaction product of an aldehyde compound and a hydroxynaphthalene compound and (B) a soluble methoxyl group-substituted cellulose ether. The agent is formed into a film having an adequate polymer scale deposition-preventive property in a single-step application. The time for the application process is shortened to improve productivity. Polymer scales can be prevented from adhering to the inner wall surfaces of the polymerization vessel even if a plenty number of batches for polymerization are repeated.
