Abstract

L'INVENTION A TRAIT AU DOMAINE DES ACCUMULATEURS ALCALINS. DES SEPARATEURS POUR ACCUMULATEURS EN POLYPROPYLENE INTRINSEQUEMENT, NON MOUILLABLES, SONT RENDUS MOUILLABLES PAR TRAITEMENT AVEC UN POLYBENZIMIDAZOLE. LES SEPARATEURS EN POLYPROPYLENE TRAITES AU POLYBENZIMIDAZONE SELON L'INVENTION ONT D'EXCELLENTES STABILITES THERMIQUES ET CHIMIQUES, ILS RETIENNENT TRES BIEN LES ELECTROLYTES ET ILS SONT PERMEABLES AUX GAZ.
