Process to prepare stable trifluorostyrene containing compounds grafted to base polymers using an alcohol/water mixture

A fluorinated ion exchange polymer is prepared by grafting at least one grafting monomer derived from trifluorostyrene on to at least one base polymer in a water/alcohol mixture. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblies used in f...
