Abstract
A fluorine-containing polymer segment includes at least one substituent for proton transfer that has one or more fluorine atoms. The fluorine-containing polymer segment is useful for forming hydrophilic polymer blocks that are used in block copolymers. Block copolymers useful for fuel cell applications incorporate the hydrophilic polymer blocks formed from the fluorine containing polymer segments.
