Abstract
An epoxy-acrylic graft copolymer useful as a paint film is prepared by the in-situ copolymerization of ethylenically unsaturated monomers including between 1% and 25% by weight of alkylated alkylol acrylamide monomer in the presence of at least 3% by weight of peroxide initiator in the absence of water. The unsaturated monomer chains are grafted by carbon-to-carbon grafts to the epoxy resin backbone. The resulting epoxy-acrylic graft copolymer is dispersed into water by adding amine, and is blended with from 1 to 40 parts by weight of aminoplast per 100 parts by weight of copolymer.
