Polymer scale preventive agent |
| abstract |
A polymer scale preventive agent for use in polymerizing a monomer having an ethylenically unsaturated double bond, comprising a condensation product of (A) an aliphatic diamine compound and (B) a quinone compound. Where the monomer is polymerized in a polymerization vessel having, on the inner wall surface, a coating film comprising said condensation product, polymer scale can effectively be prevented from being deposited not only on the liquid phase part in the polymerization vessel but also near the interface between the gas phase part and the liquid phase part, so that the thus obtained polymer can provide a molded item having few fish eyes and low in initial coloration, when the polymer is molded into a sheet or the like. |
