Abstract

a. Procédé pour lier ou assembler une pellicule de polymère fluoré et une membrane échangeuse de cations en polymère fluoré. b. Il se caractérise en ce que l'on soumet la surface d'une pellicule de polymère fluoré à un traitement hydrophile, on traite une membrane échangeuse de cations en polymère fluoré, contenant des groupes disponibles constitués par des groupes acide sulfonique ou des groupes sulfonamide, par une amine tertiaire, une base ammonium quaternaire ou un sel de ladite amine ou ladite base, puis on interpose une pellicule de polymère fluoré hydrophile poreux entre la pellicule ainsi traitée et la membrane ainsi traitée, après quoi on comprime à chaud le stratifié ainsi formé. c. Notamment fabrication ou réparation de membranes échangeuses de cations utilisées dans les procédés d'électrolyse à plusieurs compartiments et à échange d'ions.
