Abstract
A wettable microporous diaphragm for electrolysis having a base of a fluorinated resin is disclosed. This diaphragm is prepared by depositing a copolymer of an unsaturated carboxylic acid and a non-ionic unsaturated monomer in the pores of the diaphragm. The diaphragm is particularly useful for the electrolysis of alkali metal chlorides.
