Procedure

One of the membranes thus obtained (C) was treated with an aqueous ethanol solution of NaOH to convert the --SO3H groups to their sodium salt form. The membrane (C) was then spread on one side with a mixture of the following molar composition: 90% of 4-vinylpyridine, 10% of divinylbenzene and 1% (by moles with respect to the total moles of monomers) dibenzoylperoxide and then was heated in a reactor at 80° C. for 3 hours to effect copolymerization to finally obtain an 0.05 mm thick 4-vinylpyridine/divinylbenzene copolymer layer on one side of the sulfonated membrane (C).
