Abstract
A process for making a C.sub.1 -C.sub.22 dialkyl ester of a copolymer of a monoethylenically unsaturated dicarboxylic acid, anhydride or mono-C.sub.1 -C.sub.22 alkyl ester thereof, and a vinyl monomer, such as a C.sub.1 -C.sub.30 alkyl vinyl ether, which comprises reacting said copolymer with a C.sub.1 -C.sub.22 alcohol in the presence of an esterification catalyst.
