Anion-exchange polymer, preparation method therefor and anion-exchange membrane

Abstract

Provided are an anion-exchange polymer, a preparation method therefor and an anion-exchange membrane. The anion-exchange polymer comprises a chain unit I and / or a chain unit II, a structural formula of the chain unit I is , and a structural formula of the chain unit II is ; wherein A is nitrogen-containing heterocyclic ketone, Ar1 is a first aryl structure, Ar2 is a second aryl structure, M- is a trifluoroacetate ion and / or a p-toluenesulfonate ion. The anion-exchange polymer in the present application exhibits low catalyst poisoning and demonstrates excellent electrochemical performance.
