Title:
POLYMER AND PREPARATION METHOD THEREFOR, AND ANION-EXCHANGE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2023/217050
Kind Code:
A1
Abstract:
The present application 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 Ar1 and Ar2 are each independently selected from arylene derived from an aromatic compound, L1 is selected from C1-C10 alkylene, R2 is selected from a quaternary ammonium group, and R4 is selected from H or 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.
