ABSTRACT:
A process and apparatus for continuously forming a reinforced membrane of fluorinated polymers containing sulfonyl and/or carboxyl groups in melt-fabricable form and, after hydrolysis, the corresponding membrane in ion exchange form. The membrane thus formed has exceptional uniformity, and this membrane so made, when used as the membrane which separates the compartments of a chloroalkali cell, offers the advantages of low operating voltage, low power consumption and high current efficiency, and a long useful life without rupture.
