Abstract

L'invention a pour objet un polyester de masse moléculaire élevée, à faible teneur en carboxyle et utilisant une faible quantité de catalyseur. Il se prépare par un procédé en deux stades : une opération en phase fondue jusqu'à ce que la viscosité intrinsèque du prépolymère soit de 0,15 à 0,45 dl/g et une polymérisation à l'état solide en lit fluidisé jusqu'à une viscosité intrinsèque d'au moins 0,60 dl/G. Le produit polycondensé est stable et de couleur claire.
