Abstract

This invention provides crosslinked copolyester adhesives, rigid foams, protective coating, matrices for composites and dielectric for electrical circuits, and methods for making crosslinked copolyester adhesives, rigid foams, protective coatings, matrices for composites and dielectrics for electrical circuits. Two or more adherends may be bonded together using a crosslinked copolyester adhesive by first combining at least one oligomer having carboxylic acid end groups with at least one oligomer having ester end groups, where at least one of the oligomers is branched, to form a mixture. Then, the mixture is applied to the adherends to be bonded and the mixture on the adherends is cured. Next, the adherends are positioned such that the cured mixtures contact and the contacted mixtures heated to form a bond between the cured mixtures.
