Abstract

L'invention concerne des polymères à base de polyazoles, pouvant être obtenus par mise en réaction de polyazoles contenant au moins un groupe amino dont l'azote n'est pas un élément formateur de cycle d'un cycle aromatique, avec du persulfate, dont 0 à 20 % en poids, par rapport à leur teneur en polyazole, sont solubles à 130°C et 1000 hPa dans du N,N-diméthylacétamide, ainsi qu'un procédé de production et l'utilisation desdits polymères, en particulier pour la représentation de membranes électrolytiques polymères.
