Process for making C1-C22 dialkyl esters of a copolymer of a monoethylenically unsaturated dicarboxylic acid and a vinyl monomer

摘要

A process for making a C1-C22 dialkyl ester of a copolymer of a monoethylenically unsaturated dicarboxylic acid, anhydride or mono-C1-C22 alkyl ester thereof, and a vinyl monomer, such as a C1-C30 alkyl vinyl ether, which comprises reacting said copolymer with a C1-C22 alcohol in the presence of an esterification catalyst.
