ABSTRACT:
For the electrolysis of sodium chloride, the use of cation exchanger membranes is described which are composed of recurring units of ##STR1## and have an ion exchange capacity of 1.55 to 1.74 m-equivalents/g of dry polymer in the H.sup.+ form and a longitudinal expansion, during the hydrolysis of the ester form, of between 3.2 and 6.0%. A considerable decrease in the energy consumption is obtained with membranes of this type.
