Abstract
A porous diaphragm for an electrolytic cell enables, e.g., the electrolysis of NaCl to NaOH, in high concentration and in good yield, said diaphragm comprising an electrolytically acceptable porous sheet member having a total pore volume and average equivalent pore diameter adapted for electrolysis, and having an ion exchange resin fixedly deposited within the pores and occupying from 8 to 30% of the total pore volume thereof.
