(EN) HYDROXY-FUNCTIONAL THERMOPLASTIC POLYESTERS
(FR) POLYESTERS THERMOPLASTIQUES HYDROXYFONCTIONNELS
Abstract
(EN)
A biodegradable hydroxy-functional polyester is prepared by contacting a hydroxy-functional aliphatic dicarboxylic acid or a mixture of dicarboxylic acids containing hydroxy-functional aliphatic diacids, with a diglycidyl ether or diglycidyl ester in the presence of an onium catalyst in an ether solvent under conditions suitable for forming the polyester.
