    Abstract: Provided are a sulfonated poly(arylene ether) copolymer including a crosslinking structure and a polyelectrolyte membrane including the same. Particularly, a sulfonated poly(arylene ether) copolymer including a crosslinking structure in a polymer chain or at the terminal portion of the polymer chain, and a polyelectrolyte membrane including the same are provided. The polyelectrolyte membrane using the sulfonated poly(arylene ether) copolymer including the crosslinking structure, may have the same or better degree of a thermal stability, a mechanical stability, a chemical stability, a membrane forming capability, etc. than a commonly used polyelectrolyte membrane. In addition, the proton conductivity and the cell performance of the polyelectrolyte membrane may be remarkably improved than those of the commonly used polymer electrolyte. Further, the properties of the electrolyte membrane may be rarely changed, and a high measuring stability may be obtainable. The polyelectrolyte membrane may be used in a fuel cell or a secondary battery.

    Abstract translation: 提供包含交联结构的磺化聚（亚芳基醚）共聚物和包含其的聚电解质膜。 特别地，提供了在聚合物链或聚合物链的末端部分包含交联结构的磺化聚（亚芳基醚）共聚物和包含该聚合物的聚电解质膜。 使用包含交联结构的磺化聚（亚芳基醚）共聚物的聚电解质膜可以具有与常用的聚电解质膜相同或更好的热稳定性，机械稳定性，化学稳定性，成膜能力等。 。 此外，与常用聚合物电解质相比，聚电解质膜的质子传导性和电池性能可显着提高。 此外，电解质膜的性质可能很少改变，并且可以获得高的测量稳定性。 聚电解质膜可以用于燃料电池或二次电池。
