ABSTRACT:
Nongelled, amine functional polymers dispersible in water with the aid of a solubilizing acid are provided by copolymerizing (A) an ethylenically unsaturated hydroxy functional amine adduct free of epoxy groups and containing from about 1.4 to about 2.0 ethylenically unsaturated amine groups per molecule, formed from a polyepoxide having a 1,2-epoxy equivalency of from 1.4 to about 2.0 and at least a stoichiometric amount of a secondary amine with two unsaturated groups; and (B) copolymerizable monoethylenically unsaturated monomers, a portion of which is amine-functional. The water solutions are particularly useful to enable corrosion resistant coatings to be electrodeposited at the cathode.
