Abstract

PURPOSE: To remove a specified amount of F atom and ion exchange group in the surface layer of a polymer in which F atom and cation exchange group or functional group which can be readily converted into cation exchange group have been bound by treating the polymer with a reagent so as to obtain a disphragm by which high concentration alkali metal hydroxide can be electrolyzed with high current efficiency.
