Abstract
A base-functional graft polymer-containing resinous reaction product is made by incorporating an amine in a graft polymer molecule. An epoxy resin is reacted with ethylenically unsaturated monomer in the presence of a free radical initiator having hydrogen abstraction capability, to form a graft polymer resinous reaction product. The monomer may comprise a copolymerizable unsaturated amine or an unsaturated epoxide that, after the addition polymerization - grafting reaction, is reacted with a primary or secondary amine. Upon the addition of an ionizing agent and water, an aqueous dispersion or solution can be established. The resinous reaction products are useful in the formulation of coating compositions, and particularly, coating compositions useful for cathodic electrocoating.
