Abstract
PURPOSE: To manufacture the cation exchange membrane having superior capacity as membrane for electrolysis, by carrying out a series of specific treatment on perfluorocarbon group cation exchange membrane having the surface layer part or whole cation exchange radical more than one kind of exchange radical weaker acidity than -SO3H.
CONSTITUTION: After dipping perfluorocarbon group cation exchange membrane having the surface layer part or whole cation exchange radical more than one kind of exchange radical weaker acidity than -SO3H in organic solvent miscible with water and having boling point more than 30°C under 760mmHg for 2W30 hours, the above membrane is treated with heat at 50W180°C for 0.5W3 hours putting between flat board. Diene derivatives are impregnated in the above membrane at 0W100°C and partial polymerization is carried out after impregnation. The above membrane is treated with heat at 80W180°C for 0.5W60 hours putting between the flat board after dipping in PEG having 200W700 of molecular weight for 5W50 hours. When the diene derivates is possessed the radical able to convert to the exchange radical, the above radical is converted to the exchange radical by hydrolysis. Obtained exchange membrane is dipped in NaOH water solution.
