Title: RADIATION-CURABLE HYPERBRANCHED POLYMERS WITH DICARBOXYLIC ACID CORES
Abstract:
Provided are method of making a radiation-curable hyperbranched polymer. The polymer has a core comprising the esterification product of a dicarboxylic acid having structure HOOC-[C]n-COOH, wherein n is from 4 to 34, and a polyol. Also provided are methods of producing a coating on a substrate surface, the method comprising applying a coating composition comprising these polymers, as well as the coatings resulting from said methods.
