seen forhindra polymeruppbyggnad in a polimerisationsreaktor during suspensionspolymerisation of vinyl chloride

摘要

A method for preventing polymer buildup in the polymerization reactor during the suspension polymerization of vinyl chloride monomer to form polyvinyl chloride polymer and copolymers, the method comprising coating reactor surfaces in contact with the reaction medium with a material selected from the group consisting of alumina, dithiooxamide, and mixtures of these prior to carrying out this polymerization.
