POLYMERIZATION PROCESS FOR CARBOXYL CONTAINING POLYMERS

摘要

A method for polymerizing olefinically unsaturated carboxylic acids containing at least one activated carbon-to-carbon olefinic double bond and at least one carboxyl group in methylene chloride, in the presence of a free radical forming catalyst and a polyoxyethylene alkyl ether and/or a polyoxyethylene sorbitol ester surface active agent having an HLB value in the range of greater than 12.
