SUSPENSION POLYMERIZATION OF EXTENDER PVC IN PRESENCE OF EVA COPOLYMER

摘要

A method for producing polymers and copolymers of vinyl-chloride by suspension polymerization, in the presence of a small amount of specific ethylene vinyl-acetate copolymers, the catalysts, the specific ethylene vinyl-acetate copolymer, and the monomer or monomer mixture being added to the polymerization charge before the suspension agent. Polyvinyl-chloride thus obtained is suitable for reducing the viscosity of polyvinylchloride plastisols.
