Abstract

L'invention concerne de nouveaux polymères linéaires comportant plusieurs radicaux amide, imide et ester. Les résines des produits de condensation 1 d'au moins un réactif du type acide polycarboxylique cyclique à 5 chaînons 2 d'au moins un réactif du type acide polycarboxylique éthyléniquement non saturé à cycle lactame à ou 6 chaînons, 3 d'au moins un réactif aminé polyfonctionnel cyclique à 5 ou 6 chaînons, 4 d'au moins un glycol, 5 d'au moins un autre composé hydroxylé polyfonctionnel et 6 d'au moins un autre réactif du type ester d'acide carboxylique. Les résines sont appropriées à l'émaillage isolant de fils pour électro-aimant.
