Abstract
A bipolar membrane is produced by fastening an anion exchange membrane to a cation exchange membrane with the aid of an ion-permeable adhesive, by a process in which an aqueous solution of a polyvinylamine is used as the adhesive, and the bipolar membrane, which consists of two ion exchange membranes and the film-like adhesive, is subjected to electrodialysis.
