TRIFLUOROSTYRENE AND SUBSTITUTED TRIFLUOROSTYRENE COPOLYMERIC COMPOSITIONS AND ION-EXCHANGE MEMBRANES FORMED THEREFROM

摘要

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