Abstract
A composition that includes a non-gelled copolymer that includes one or more residues of a first polymerizable ethylenically unsaturated monomer containing a pendant amide, ester or carboxylic acid group. The nearest neighboring monomer residues of the majority of the first monomer residues along the copolymer molecule do not contain pendant carbonyl functional groups. The amide, ester or carboxylic acid group of the residues of the first monomer are the post polymerization transesterification, transamidification or hydrolysis reaction product of a C-Calkyl ester group in the unreacted first monomer with a compound selected from amine functional compounds and hydroxy functional compounds. The reacted copolymer is substantially free of cyclical structures resulting from the transesterification, transamidification or hydrolysis reaction. The compositions may be thermosetting compositions useful in multi-layer composite coatings.
