Abstract

Un procédé permet de préparer des polycondensés d'acide aspartique à biodégradabilité améliorée par polycondensation thermique d'acide aspartique finement pulvérisé en phase solide, à des températures comprises entre 180 et 250 ~C, jusqu'à ce qu'au maximum 70 % en poids de la quantité d'eau théoriquement possible produite pendant la polycondensation aient été enlevés du mélange de réaction. L'invention concerne également l'utilisation des polycondensés ainsi obtenus comme additifs de produits de lavage et de nettoyage et comme agents anti-incrustation.
