ABSTRACT OF THE DISCLOSURE A two-step lamination process is disclosed for the manufacture of a cation permeable membrane having areas of thin wall construction, the membrane having a cation exchange polymer matrix with a reinforcement fabric embedded therein. The process comprises laminating at 150-350°C a first film and a reinforcement fabric, the latter contacting a porous support material, using a vacuum that draws the first film onto the reinforcement fabric and partially into contact with the porous surface, separating the reinforcement fabric and first film from the porous support material whereby a laminate is obtained with holes in at least 5% of the surface area of the film, and then laminating the resulting structure to a second film. The films are of a fluorine-containing polymer with pendant side chains having sulfonyl or carboxyl groups. The membrane obtained is substantially free of holes, and has utility in membrane ion exchange, reverse osmosis devices or in electrolytic cells such as chloralkali cells.
