ABSTRACT:
Epoxy ether-amino acrylate polymers dispersible in water with the aid of an acid are provided by etherifying a polyepoxide with an ethylenically unsaturated alcohol to provide an unsaturated hydroxy-functional polyether containing from about 1.2 to about 2.0 ethylenically unsaturated ether groups per molecule. This polyether is copolymerized in organic solvent solution with monoethylenically unsaturated monomers including amine-functional monomer to provide an amine copolymer which is solubilized in water with an acid at a pH of 5.0-7.0. These water dispersions which are formed can be electrodeposited at the cathode to form valuable coatings despite the approximately neutral pH of the bath from which they are deposited.
