PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT VINYL COPOLYMERS

摘要

Process for Producing High Molecular Weight Vinyl Copolymers Disclosed is a method of producing high molecular weight copolymers from vinyl monomers such as vinylpyridine and styrene by emulsion polymerization which comprises combining the monomers with a particular surfacant, a polymerization initiator in an aqueous medium at a solids level of 5-50% by weight, and carrying out the polymerization at a pH of 10-14 at a temperature of 40-90.degree.C until the conversion is greater than 90%.
