摘要： A multiblock copolymer includes a polysulfone repeating unit of formula (1) below; a sulfonated polysulfone repeating unit of formula (2) below; and an ethylenic unsaturated group at a terminal of the multiblock copolymer: where l and m are integers of 1-200; each of R1 through R4 is independently hydrogen, fluorine, or a C1-C10 alkyl group that is unsubstituted or substituted by at least one fluorine atom; and X represents a tetraalkylamine cation. Provided are a method of preparing the multiblock copolymer, a polymer electrolyte membrane prepared from the multiblock copolymer, a method of preparing the polymer electrolyte membrane, and a fuel cell including the polymer electrolyte membrane. The polymer electrolyte membrane that has a high ionic conductivity and good mechanical properties and minimizes crossover of methanol can be manufactured at a low cost. In addition, the structure of the multiblock copolymer can be varied to increase selectivity to a solvent used in a polymer electrolyte membrane.
