ABSTRACT:
A method for producing a fluorinated copolymer membrane comprising a first layer made from a fluorinated copolymer having pendant sulfonylchloride groups and a second layer made from a fluorinated copolymer having sulfonylfluoride groups. The membrane is treated with a reducing agent to introduce carboxylic acid groups onto the surface of said first layer. The membrane may be used as a cation exchange membrane. If necessary, a supporting material may be embedded in the second layer.
