ABSTRACT OF THE DISCLOSURE A cation-exchange membrane is prepared by swelling a fluorinated polymer membrane having cation-exchangeable groups in an organic solvent, removing the solvent from the swollen membrane and impregnating the swollen membrane with a monomer with or without a crosslinking agent and a polymerization initiator and polymerizing the monomer in the membrane. The membrane so obtained is preferably swollen with a water miscible organic solvent and then, the solvent is removed from the membrane.
