Process to prepare stable trifluorostyrene containing compounds grafted to base polymers

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 the presence of a fluorosurfactant. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblie...

Zusammenfassung: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 the presence of a fluorosurfactant. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblies used in fuel cells.
