Patent

CA 2675368

A polyester polymer comprising alkylene arylate units, said polymer having an It. V. of at least 0.72 dl/g, a vinyl ends concentration of at least 0.8 microequivalents per gram, an AA generation rate of less than 20 ppm are prepared by addition of a catalyst deactivator either late in the polycondensation or upon remelting of a solid polyester polymer.

L'invention concerne un polymère de polyester comportant des unités d'arylate d'alkylène, ledit polymère ayant une viscosité intrinsèque d'au moins 0,72 dl/g, une concentration de terminaisons vinyliques d'au moins 0,8 microéquivalent par gramme et un taux de production de AA inférieur à 20 ppm. Lesdits polymères sont préparés par l'ajout d'un désactivateur de catalyseur soit ultérieurement dans la polycondensation, soit lors de la refusion d'un polymère de polyester solide.
