FUNCTIONALIZED POLYAZOLES, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF

摘要

The invention relates to functionalized polyazoles containing recurrent imidazole units of general formula (1a) and/or (1b) and/or (1c) and/or (2), in which the radicals Ar, Ar1 and Ar2 represent tetravalent, divalent, or trivalent aromatic or heteroaromatic groups, Y represents a bond or a group comprising 1 to 20 carbon atoms, v represents a whole number between 1 and 1 0, and Z represents a group of general formula (3) or (4), in which R1 and R2 independently represent a carbon atom or a group comprising 1 to 20 carbon atoms. The inventive functionalized polyazoles are characterized by the fact that the polyazole is soluble in organic solvents. The invention also relate s to intermediate products and methods for producing said polyazoles as well a s polymer electrolyte membranes and fuel cells containing the inventive polyazoles.
