Abstract
L'INVENTION CONCERNE UN PROCEDE DE FABRICATION D'UNE MEMBRANE QUI S'OPPOSE A LA DIFFUSION DE GAZ ET EST CONDUCTRICE DE CATIONS EN MILIEU ALCALIN ET D'ANIONS EN MILIEU ACIDE. ON PREPARE UNE SOLUTION DE POLYSULFONE DANS DU METHYL-PYROLIDON, ON MOUILLE DE LA POUDRE D'ACIDE POLYANTIMONIQUE DE METHYL-PYROLIDON, ON MOUD LA POUDRE MOUILLEE, ON PREPARE UNE SUSPENSION EN PARTANT DE LA POUDRE AINSI MOUILLEE ET MOULUE ET DE METHYL-PYROLIDON, ON MELANGE LA SUSPENSION AVEC LA SOLUTION, ON DEVERSE LE LIQUIDE VISQUEUX AINSI OBTENU SUR UNE PLAQUE, ON LAISSE S'EVAPORER LE METHYL-PYROLIDON JUSQU'A CE QU'UNE MEMBRANE EN FORMATION COMMENCE A SECHER, ON ELIMINE LE RESTE DU METHYL-PYROLIDON PAR LESSIVAGE ET ON ENLEVE LA MEMBRANE DE LA PLAQUE.
