Title (EN) PROCESS FOR IMPROVING THE THERMAL AND LIGHT STABILITY OF POLYESTERS
(FR) METHODE POUVANT AMELIORER LA STABILITE A LA CHALEUR ET A LA LUMIERE DE POLYESTERS
Abstract: front page image
(EN)The present invention describes a process for improving the thermal and light stability of polyesters, especially polyester fibers, which comprises adding to the polyesters a chain extender. Especially preferred chain extenders are dianhydrides, alcohols and hindered phenolic aromatic phosphates or mixtures thereof.
(FR)La présente invention concerne une méthode pouvant améliorer la stabilité à la chaleur et à la lumière de polyesters, notamment de fibres de polyester, qui consiste à ajouter aux polyesters un allongeur de chaîne. Des allongeurs de chaîne particulièrement préférés sont constitués de dianhydrides, d'alcools et de phosphates phénoliques aromatiques entravés ou de leurs mélanges.
