摘要: A polyarylene copolymer having a sulfonic acid group which has high proton conductivity and reduced swelling in hot water and reduced shrinkage in drying; a solid polymer electrolyte and a proton conductive membrane comprising the copolymer; and a membrane-electrode assembly using these.
The polyarylene block copolymer comprises a polymer segment (A) having a sulfonic acid group, and a polymer segment (B) having substantially no sulfonic acid group, the polymer segment (B) having substantially no sulfonic acid group comprising a structural unit represented by the following formula (1).摘要翻译: 具有磺酸基的聚亚芳基共聚物,其具有高质子传导性,并且在热水中膨胀减少并且减少了干燥收缩; 固体聚合物电解质和包含所述共聚物的质子传导膜; 以及使用这些的膜 - 电极组件。 聚亚芳基嵌段共聚物包含具有磺酸基的聚合物链段(A)和基本上不含磺酸基的聚合物链段(B),所述聚合物链段(B)基本上不含有磺酸基, 以下公式(1)。
