Abstract: A cation exchange membrane containing functional groups of both the sulfonic acid and carboxylic acid radicals which allows the membranes to maintain its conductivity throughout the entire pH range. This unique property gives this high capacity -pH insensitive membrane particular value in electrolytic cells as hydraulic diaphragms to separate a basic solution from an acid solution as is encountered in caustic-chlorine cells or other type cells which electrolytically decompose neutral salt solutions such as sodium sulfate into their basic and acidic components of caustic soda and sodium acid sulfate. The capacity of this membrane is much higher than the presently known sulfonic acid salt types.
