COMPOSITE DIAPHRAGM MATERIAL COMPRISING HALOGENATED AND SULFONATED STYRENE DIVINYL BENZENE LYMER

摘要

Novel composite material comprising a supporting matrix of inert fibers impregnated with a halogenated copolymer of divinyl benzene and styrene containing sulfonic acid groups copolymerized directly on the fiber material in the absence of a solvent which remains dimensionally stable under electrolyisi conditions in diaphragm cells and the method of making them and the method of electrolyzing alkali metal halide solutions in a diaphragm cell equipped with a diaphragm made of said impregnated composite diaphragm material.
