Abstract

Une membrane polymere poreuse comprend un poly-1,3,4-oxadiazol de formule generale: (FORMULE) ou R et R'sont des radicaux bivalents dont l'un au moins est capable de rendre ces poly-1,3,4-oxadiazols solubles dans des solvants organiques. Un procede de fabrication d'une telle membrane consiste a preparer une solution de 10 a 20% de ce poly-1,3,4-oxadiazol dans un solvant organique par exemple la N-methylpyrrolidone et a appliquer ensuite cette solution sur une surface de formation avec coagulation ulterieure dans le milieu d'un precipitant. Cette solution peut contenir LiCl ou P2O5 en une quantite de 0,1 a 5% en poids de la solution. Les membranes peuvent etre utilisees dans des technologies differentes pour la concentration et la separation de solutions, la sterilisation de preparations medicinales le traitement d'eaux residuelles et de l'eau.
