Patent ID: 7619040

Claim:
A method of making a copolymer comprising the steps of: (a) providing a monomer composition comprising: (i) at least one monomer having the formula CH 2 ═CR 1 R 2 , wherein R 1 is a linear or branched C 1 to C 4 alkyl, and R 2 is selected from the group consisting of methyl, linear, cyclic or branched C 2 to C 20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and (ii) at least one monomer having the formula CH 2 ═CH—C(O)—R 3 ; (b) polymerizing the monomer composition to form a copolymer; and reacting the copolymer by reacting the monomer (ii) functionality with a reactant selected from hydroxy functional compounds and amine functional compounds to form a non-gelled reacted copolymer, wherein —C(O)—R 3 is a group that is capable of a reaction selected from transesterification, transamidification and hydrolysis with the reactant.
