Abstract

L'invention concerne un procédé pour la préparation de polyesters de poids moléculaire élevé par réaction d'acides dicarboxyliques ou de leurs dérivés avec des diols en présence de catalyseurs. On utilise selon l'invention comme catalyseur une combinaison de composés du manganèse, du magnésium et du titane.
