A method of making a monomer solution of styrene sulfonic acid or the pyridine salt of styrene sulfonic acid or mixtures of both in an organic solvent, said solution being suitable for producing cation exchange membranes. The method comprises the steps of dissolving a metal salt of styrene sulfonate in said organic solvent and pyridinium styrene sulfonate. The mixture solution is reacted under conditions that generate a salt byproduct precipitate and the reactant product solution is collected. Embodiments of the present invention provide for cation exchange membranes and processes for their manufacture. Membranes made by the processes described herein combine low resistance and high permselectivity which make them highly effective for membrane components in desalination of water by electrodialysis (ED), as a power generating sources in reverse electrodialysis and as separators in fuels cells.
