Surfactant-containing acetoacetoxy-functional polymers (SAAPs) are described . The acetoacetoxy-functional polymer may be a surfactant-containing enamine- functional polymer and more preferably a surfactant-containing, polymeric (polyamino)enamine (PPAE). The PPAE is the reaction product of a surfactant- containing acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The polymers may be prepared as waterborne polymer compositions, such as latexes. The waterborne polymer compositions can be prepared with high solid s content while maintaining low viscosity. Waterborne polymer compositions containing the polymers of the inventions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, and adhesives. Wh en used in coating formulations, the polymers of the invention provide adhesion and crosslinking in the final film or coating. The film or coating may be cured at ambient temperatures or may be thermally cured. |
