    摘要: Provided is an anion-exchange membrane including: a substrate composed of a film of ultrahigh molecular weight polyolefin; and a graft chain having the following structural unit.

    L 1 to L 5 are each independently a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkanol group having 1 to 4 carbon atoms, or a specific functional group including an anion-exchange group, and an example of the functional group is -Z 2 -M 1 -Z 1 (R 1 )(R 2 )(R 3 ). R 1 to R 3 are directly bonded to Z 1 and are each independently an alkyl group having 1 to 8 carbon atoms or an alkanol group having 1 to 8 carbon atoms. M 1 is a linear hydrocarbon chain having 3 to 8 carbon atoms, Z 1 is a nitrogen atom or a phosphorus atom, and Z 2 is a nitrogen atom bonded to one hydrogen atom, an oxygen atom, or a sulfur atom. L 6 is a hydrogen atom, a methyl group, or an ethyl group.
