Abstract

Procédé de préparation de résines polyesters ou polyestérimides solubles dans l'eau, par polyestérification d'au moins un acide polycarboxylique, ou un composé susceptible d'en engendrer, avec au moins un polyalcool, puis neutralisation au moins partielle des groupes carboxyles résiduaires par l'ammoniac ou une amine. On emploie comme acide polycarboxylique de départ un acide comportant au moins un noyau pyrrolidone, notamment le diacide lactame obtenu par condensation de l'acide itaconique avec la méthylène-dianiline. Application à la fabrication de vernis pour émaillage de fils électriques.
