Abstract

L'invention concerne un procédé pour la préparation de polyester d'acides dicarboxyliques et de glycols. Dans le procédé selon l'invention, on fait réagir un diester d'alkyle inferieur en C1 -C4 d'un acide dicarboxylique consistant pour au moins 90 moles % en acide téréphtalique avec un alkylèneglycol en C2 -C10 consistant pour au moins 90 moles % en éthylèneglycol ou tétraméthylèneglycol et on effectue ensuite la polycondensation du diester de glycol de l'acide dicarboxylique et/ou son condensat de bas poids moléculaire obtenus en présence de A un p-formylbenzoate d'alkyle inférieur en C1 -C4 en quantité d'environ 50 à 1000 ppm, B un isophtalate de dialkyle inférieur en C1 -C 4 en quantité d'environ 50 à 1000 ppm et C de l'acide p-toluique et/ou un téréphtalate de monoalkyle inférieur en C1 -C4 en quantité de plus d'environ 30 ppm, la quantité totale des composés A, B et C n'étant pas supérieure à environ 20 000 ppm.
