    摘要： A fluorinated ion exchange polymer prepared by grafting a monomer on to a base polymer, wherein the grafting monomer is selected from the group consisting of structure 1a, structure 1b and mixtures thereof, (INSERT 1a and 1b HERE) wherein Y is selected from the group consisting of —RFSO2F (sulfonyl fluoride), —RFSO3M (fluorosulfonic acid or salt), RFSO2NH2 (fluorosulfonamide), and —RFSO2N(M)SO2R2F (imide); wherein M is H, an alkali cation, or ammonium; and RF and R2F groups are perfluorinated or partially fluorinated, and may optionally include ether oxygens; and n is between 1 and 2 for 1a, or n is between 1 and 3 for 1b. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblies used in fuel cells.
