Functionalized polyazoles, method for the production thereof, and use thereof

A functionalized polyazole comprising recurring imidazole units of the general formula

• where the radicals Ar, Ar1 and Ar2 are tetravalent, divalent or trivalent aromatic or heteroaromatic groups,
• Y is a bond or a group having from 1 to 20 carbon atoms,
• v is an integer from 1 to 10 and
• Z is a group of the general formula
• where R1 and R2 are each, independently of one another, a hydrogen atom or a group having from 1 to 20 carbon atoms, characterized in that the solubility of the polyazole in N,N-dimethylacetamide is at least 0.1 g, based on 100 g of solution, at 100° C.
