Title (EN) PROCESS FOR PREPARING HYDROXY-FUNCTIONALIZED POLYESTERS
(FR) PROCEDE PERMETTANT DE PREPARER DES POLYESTERS HYDROXY-FONCTIONNALISES
Abstract: front page image
(EN)A process for preparing a thermoplastic hydroxy-functionalized polyesters comprises contacting a dicarboxylic acid or a mixture of dicarboxylic acids with a diepoxide in the presence of a monofunctional carboxylic acid and a catalyst, and in the absence of a solvent under conditions sufficient to form the hydroxy-functionalized polyesters.
(FR)Selon un procédé permettant de préparer des polyesters hydroxy-fonctionnalisés thermoplastiques, on met en contact un acide dicarboxylique ou un mélange d'acides dicarboxyliques avec un diépoxyde en présence d'un acide carboxylique monofonctionnel et d'un catalyseur, et en absence de solvant, dans des conditions suffisantes pour former les polyesters hydroxy-fonctionnalisés.
