METHOD FOR POLYMERIZING ETHYLENICALLY UNSATURATED MONOMERS

摘要

In the polymerization of at least one ethylenically unsaturated monomer other than vinyl chloride, deposition of polymer scale on the inner walls of a polymerization reactor and other surfaces coming into contact with the monomer is effectively inhibited, regardless of the type of polymerization, by coating prior to the polymerization, the surfaces with at least one compound selected from organic electron-donor compounds (A) and organic electron-acceptor compounds (B), the compound or compounds having been or being brought into contact with a compound (C) comprising an oxidizing agent, a reducing agent, an acid or a base, or having been or being irradiated with ultraviolet light. A product obtained from the compound or compounds (A) and/or (B) by reaction with compound (C) or by irradiation with ultraviolet light can be added to the polymerization mixture.
