カルボニル末端基の量を減らしたフッ素化イオノマー

摘要

The present invention is a fluoropolymer comprising a plurality of pendent groups terminating in -CF₂SO₃X, -CF₂SO₂F, or combinations thereof, where X is selected from a group consisting of H⁺ and a monovalent cation, and at least one -CF₂Y end group, where Y is selected from a group consisting of a chlorine atom, a bromine atom, an iodine atom, a nitrile group, and an -SO₃X group.
