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.
