ABSTRACT:
Monoethylenically unsaturated beta-carbonyl-containing carboxyl functional monomers and addition polymers containing them and other monoethylenically unsaturated monomers are disclosed, as are methods of coating substrates with the polymers to provide films of improved water resistance. The monomers are especially stable in the form of a salt with a volatile base, and the removal of the base when a polymer containing the monomer is cured causes decarboxylation, and the removal of the carboxyl groups improves the water resistance.
