Abstract
A method for making a resilient ion exchange membrane comprising polymerizing a composition containing at least an ionic surfactant monomer having an ethylenic group and a long hydrophobic alkyl group filling the pores of and covering the surfaces of a porous substrate. The hydrophobic long alkyl group in the ionic surfactant monomer provides ion exchange membranes with improved mechanical properties, and good chemical stability.
