Abstract
L'invention concerne des résines de polyesters insaturés pouvant piéger de l'air ou d'autres gaz inertes pour former des mousses structurelles. Selon l'invention elles contiennent dans la chaîne polymérique, 0,1 à 20 % en moles de groupes amide et/ou amine provenant de la réaction de l'acide polycarboxylique et/ou d'un alcool polyvalent avec un composé organique difonctionnel contenant au moins un atome terminal d'azote basique, et elles ont un indice d'acidité compris entre 5 et 90 mg de KOH/g et un poids moléculaire compris entre 500 et 5 000. L'invention permet notamment d'obtenir des mousses stables dans le temps et ayant de bonnes caractéristiques mécaniques.
