FLUORINATED IONNEXCHANGE POLYMER
Document Type and Number:
Japanese Patent JPS53132089
Kind Code:
A
Abstract:
Fluorinated ion exchange polymers which have pendant side chains which contain groups wherein W is F or CF3, and R is an inonizable group, or which have such pendant side chains and also pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency.
