Abstract

PURPOSE:To obtain a uniform bipolar membrane having improved mechanical stability, durability, hydrolysis efficiency, and electrical conductivity, by introducing cation exchange groups into the side uncovered with a film, and then anion exchange groups into the other side. CONSTITUTION:The reinforcing fabric 2 is passed through the impregnation bath 5 consisting mainly of styrene, divinylbenzene, etc., brought into contact with the covering film 6 at the nip point of the squeeze roll 8 and the winding roll 9, and wound onto the roll 9 at a constant speed under a given pressure. The impregnated liquid is polymerized at a given temperature and pressure, to form a composite comprising the two layers of a high polymer membrane and a covering film in close contact. The composite is then immersed in a sulfonation bath to sulfonate the opposite side of the film, and the side peeled from the film is haloalkylated or aminated to introduce anion exchange groups.
