Abstract

The present invention is directed to a coating composition comprising a polymer that comprises an oligomeric macromonomer and a core from which the oligomeric macromonomer extends, wherein the oligomeric macromonomer comprises reactive functional groups and has an average functionality ranging from 1.0 to 30, and wherein the core is <10 weight % of the total polymer weight.
