Process to prepare stable trifluorostyrene containing compounds grafted to base polymers using a solvent/water mixture
Abstract
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 organic solvent/water mixture. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblies used in fuel cells.
