Abstract
(EN)
A cobalt/aluminum catalyst for the polymerization of polyesters of terephthalic acid and an ethylene glycol, a process for the preparation of such catalysts, a process for the polymerization of terephthalic acid and an ethylene glycol, a process of spinning fibers of such polyesters where reduced spinneret wiping is achieved, and fibers of such polyesters containing catalyst residues of cobalt/aluminum, and films or bottles of said polyesters.
(FR)
L'invention porte sur un catalyseur au cobalt/aluminium pour la polymérisation de polyesters d'acide téréphtalique et d'un éthylène glycol, sur un procédé de production de ces catalyseurs, sur un procédé de polymérisation de l'acide téréphtalique et d'un éthylène glycol, sur un procédé de filage de fibres de ces polyesters où est réalisée la sèche de la filière. Elle a également trait à des fibres de ces polyesters contenant des résidus catalytiques de cobalt/aluminium et à des films ou des bouteilles constitués desdits polyesters.
