发明名称 IMPROVED PROCESS FOR PRODUCING POLYVINYL CHLORIDE
摘要 PROBLEM TO BE SOLVED: To provide an aqueous suspension polymerization process for producing a polymer having an improved color, especially a polyvinyl chloride and a PVDF product, and a process utilizing a combination of an N-substituted hydroxylamine chain stopper and a fixed polymerization initiator. SOLUTION: The improved process method is characterized in that vinyl chloride alone or a mixture of vinyl chloride and <50% another vinyl monomer is subjected to an aqueous suspension polymerization, its polymerization initiator comprises at least one kind of a compound selected from a dialkyl peroxydicarbonate, a peroxy-t-alkanoate and a diacyl peroxide, and further a mono- or disalkyl-substituted N-hydroxylamine is used as the polymerization initiator or the chain stopper.
