Carbamate-functional polymer, curable coating composition thereof, and method of preparing the polymer |
摘要 |
The present invention is directed to a carbamate-functional polymer that is used to promote the acid etch resistance and recoat adhesion of coating compositions. The polymer is the reaction product of a first compound having a hydroxyl group and a carbamate group, and a carboxylic acid anhydride that is reactive with the hydroxyl group of the first compound. The first compound and the carboxylic acid anhydride form an intermediate compound having a carboxylic acid group and the carbamate group. A second compound has an epoxy group that is reactive with the carboxylic acid group of the intermediate compound for preparing the carbamate-functional polymer. The present invention is also directed to a curable coating composition including the polymer and a method of preparing the polymer.
