ABSTRACT:
A modified cationic vinyl polymer prepared by the copolymerization of a polymerizable styrene, maleic anhydride and an alkyl acrylate, which polymer is then reacted with certain amino alcohols and/or certain difunctional amines containing a tertiary nitrogen atom followed by reaction with certain monoepoxy compounds. The modified vinyl polymer finds utility in electrocoating applications, particularly for anodic-soluble metals, such as copper and copper alloys wherein the vinyl polymer, in amounts varying between about 40% and 95%, by weight, is combined with about 4.0% to about 50%, by weight, of a substantially fully etherified, substantially fully methylolated aminotriazine cross-linking agent and from about 1% to about 20%, by weight, of a neutralizing agent such as a mineral acid or an organic acid in an aqueous dispersion.
