Patent ID: 7989579

Claim:
A method for the production of a functionalized polytriazole polymer comprising the steps of: a) mixing a hydrazine salt with at least one of a dicarboxylic acid and a dicarboxylic acid derivative in polyphosphoric acid to obtain a solution; b) heating the solution in a protective gas atmosphere at temperatures in a range between 150° C. and 190° C. to form polyhydrazides and adding at least one primary amine to the solution to form polytriazoles, wherein said primary amine has at least one sulfonic acid group and is selected from a group consisting of aromatic primary amines and heteroaromatic primary amines, wherein at least one of said primary amines has a structure of the formula H 2 N—Ar—YqZ wherein Ar is an aromatic or heteroaromatic group, Y is a bond or a group with 1 to up to 20 carbon atoms, Z is a group of the formula —SO 3 R 1 , wherein R 1 is a hydrogen atom or an alkali metal, and q is a whole number between 0 and 4; and c) precipitating a polymer from the solution.
