ABSTRACT:
A fluorinated cation exchange membrane comprising one or more layers of an ion-conductive film and where one or more layers has adhered therein a fabric reinforcement made from fully ion conductive yarn that is oriented and then at least partially hydrolyzed, the film and the yarns being made of melt-fabricable fluorinated cation exchange resin precursors having a mole ratio of non-functional to functional monomer of 2.8-11.8:1, the mole ratio in the film adjacent to the fabric being different from that of the fabric by no more than three units, where the membrane is employed in the process of electrolyzing alkali metal halides.
