Abstract
PURPOSE:To obtain a high current efficiency, by forming two layers of the film material of the fluorocarbon copolymer having a specific ion exchange capacity in parallel to the surface and by giving specific side chain structure (a) and specific side chain structure (b) to one and the other layers respectively. CONSTITUTION:The exchange radical of a specific side chain structure (expression I) which exists in the film material of the fluorocarbon copolymer having ion exchange capacity 1.1-2 milliequivalent per gram of dry resin is substituted by -O(CF2)nI(n=2-5), and further, it is converted to a specific side chain structure (expression II). Therefore, layers are distinguished from the adjacent layers by kinds of existing exchange radical, and two layers are formed in parallel to the surface. Then, when the layer where the specific side chain structure (expression II) exists is directed toward the anode side to perform electrolysis of alkali chloride, current efficiency is improved considerably.
