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.Process for the preparation of water-soluble polyester or polyester ester resins, by polyesterification of at least one polycarboxylic acid, or a compound capable of generating it, with at least one polyalcohol, then at least partial neutralization of the residual carboxyl groups by l ammonia or an amine. An acid comprising at least one pyrrolidone nucleus, in particular the diacid lactam obtained by condensation of itaconic acid with methylene-dianiline, is used as the starting polycarboxylic acid. Application to the manufacture of varnish for enamelling electric wires.
