ABSTRACT:
The present invention is a process for modifying a fluorinated cation exchange membrane by irradiation of the membrane in its salt form with a sufficient dose of non-spark-producing radiation to increase the current efficiency in the use of the membrane for electrolyzing sodium chloride solution to produce high concentrations of caustic.
