Abstract

PURPOSE: To obtain an excellent membrane of multi-layer structure which shows high current efficiency and stable voltage even in an alkali of high concn. by making three or more layers parallel with one another and allowing sulfonic acid groups to exist at one end layer, carboxylic acid groups at the other one, and groups having cation exchange capacity at the remaining ones.
