ABSTRACT:
A diaphragm for electrolyzing alkali metal chloride solutions is provided which is one or more layers of a porous support, coated with a perfluoro ion exchange polymer and then wet with a wetting solution which has a surface tension of 22 to 45 dynes/cm. The wetting solution is preferably an aqueous alcohol and most preferably aqueous 3-6.5% butanol. The wetting solution assists in initial water penetration into the pores of the diaphragm, rendering the diaphragm hydrophilic so as to resist gas locking and premature shutdown of the electrolytic cell.
