Abstract

L'invention concerne la préparation de résines pour l'électrodéposition à la cathode. Selon l'invention on fait réagir des polycondensats non saturés ou des polymères de diènes contenant des groupes hydroxyles tels que des esters contenant des groupes hydroxyles avec des composés ayant des groupes isocyanates libres et des atomes d'azote tertiaires et éventuellement avec des composés comportant des groupes isocyanates libres et des doubles liaisons oléfiniques. Le procédé selon l'invention permet d'obtenir des résines pour l'électrodéposition cathodique à partir de matières premières accessibles et relativement bon marché.
