The invention discloses a side chain type polyphenylene ether containing a benzimidazole structure, a preparation method and a homogeneous anion exchange membrane. The molecular structure of the side chain type polyphenylene ether containing benzimidazole structure is shown in formula (I): the number average molecular weight of the side chain type polyphenylene ether containing benzimidazole structure is Mn=40,000～100,000; formula middle, m=3, 4, 5 or 6. The present invention also provides the prepared homogeneous anion exchange membrane, the prepared anion exchange membrane has the advantages of excellent ion conductivity, low swelling rate, high tensile strength, high monovalent anion selectivity and the like. |
