Abstract
A method for producing glycidic ether-containing amorphous and/or semi-crystalline copolyesters involves first producing a hydroxyl-functional amorphous or semi-crystalline copolyester, and then converting such hydroxyl-functional copolyester with an epihaloalkane to form the desired glycidic ether-containing copolyester.
