The present invention relates to a process for increasing the molecular weight and for the modification of polycondensates, to the use of an additive blend effecting the increase in molecular weight without imparting color to the polycondensates as well as to the polycondensates obtainable by that process. The additive blend contains at least one bis-acyllactam, at least one phosphite, phosphinate or phosphonate; or at least one benzofuran-2-one type compound or at least one phosphite, phosphinate or phosphonate and one benzofuran-2-one type compound.
La présente invention concerne un procédé pour augmenter le poids moléculaire et pour modifier des polycondensats, l'utilisation d'un mélange d'additifs conduisant à l'augmentation de poids moléculaire, sans colorer les polycondensats, ainsi que les polycondensats pouvant être obtenus selon ce procédé. Le mélange d'additifs contient au moins une bis-acyllactame, au moins un phosphite, phosphinate ou phosphonate ou au moins un composé de type benzofurane-2-one ou au moins un phosphite, phosphinate ou phosphonate et un composé de type benzofurane-2-one.
