COPOLYMERIC COMPOSITIONS OF TRIFLUOROSTYRENE, SUBSTITUTED TRIFLUOROSTYRENE AND SUBSTITUTED ETHYLENE, AND ION-EXCHANGE MEMBRANES FORMED THEREFROM

摘要

Polymeric compositions are derived from copolymers of substituted and unsubstituted alpha , beta , beta -trifluorostyrene, with a variety of substituted ethylene monomers. These compositions are suitable for use as membranes, particularly as ion-exchange membranes, and more particularly as solid polymer electrolytes in electrochemical applications, such as, for example, electrochemical fuel cells.
