Abstract
Abstract Disclosed are copolyesters derived from 100 mole % of a dibasic acid component, at least 2 mole % of which is the reaction product of ethylene and at least one dialkyl ester of an aliphatic or cycloaliphatic dibasic acid, said dibasic acid containing from 3 to 22 carbon atoms and the alkyl groups of wich contain from 1 to 8 carbon atoms, and 100 mole % of at least one aliphatic or alicyclic glycol having 2 to 12 carbon atoms. These polyesters are useful as adhesives.
