Abstract: The present invention relates to synthetic membranes and use of these synthetic membranes for isolation of volatile organic compounds and purification of water. The synthetic membrane includes a hydrophobic polymer layer located on a polymeric membrane support layer. The invention includes a method of isolating volatile organic compounds with the synthetic membrane by contacting a volatile organic mixture with the hydrophobic polymer layer of the synthetic membrane and removing volatile organic compounds from the polymeric membrane support layer of the synthetic membrane by a process of pervaporation. The invention also includes a method of purifying water with the synthetic membrane by contacting an ionic solution with the hydrophobic polymer layer of the synthetic membrane and removing water from the polymeric membrane support layer of the synthetic membrane by a process of reverse osmosis. The invention also relates to methods of isolating non-polar gases by gas fractionation.

Abstract: 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.
