Abstract: A process for producing a resilient ion exchange membrane. The process comprises the steps of (1) selecting a porous matrix, (2) saturating the porous matrix with a homogenous solution comprising a mixture of: (i) a hydrophilic ionic monomer, (ii) a hydrophobic cross-linking oligomer and/or a comonomer, (iii) a free radical initiator, and (iii) a solvent for solubilizing the hydrophilic ionic monomer, the hydrophobic cross-linking oligomer and/or comonomer, and the free radical initiator into a homogenous mixture. (3) removing excess homogenous solution from the saturated porous matrix, (4) stimulating release of free radicals from the free radical initiator thereby initiating a polymerization reaction to form a cross-linked ion-transferring polymer substantially filling the pores and covering the surfaces of the porous matrix thereby forming a membrane, (5) washing the membrane to remove excess solvent, and (6) optionally bathing the washed membrane in a sodium chloride solution to selectively cross-link sodium or chloride ions to and within the ion-transferring polymer.
