摘要:The present disclosure relates to a polymer and a preparation method therefor, and an anion-exchange membrane. The polymer comprises a structural unit represented by Formula (1) and a structural unit represented by Formula (2), wherein Ar 1 and Ar 2 are each independently selected from an arylene group derived from an aromatic compound, L 1 is selected from a C1-C10 alkylene, R 2 is selected from a quaternary ammonium group, and R 4 is selected from H or a C1-C7 alkyl. A high-performance anion-exchange membrane having high ion conductivity, low swelling, and strong alkali resistance can be obtained from the polymer of the present application, and no noble metal catalyst is required in a synthesis method, which is environment-friendly and simple; the present application has a broad application prospect.
