Abstract
A method for the production of a functionalized polytriazole polymer, particularly a poly(1,2,4-triazole)-polymer, includes the steps of (a) mixing a hydrazine salt, particularly hydrazine sulfate, with at least an aromatic and/or heteroaromatic dicarboxylic acid and/or at least a dicarboxylic acid derivate in polyphosphoric acid and if necessary further components for obtaining a solution; (b) heating the solution in a protective gas atmosphere for obtaining polyhydrazides and adding aromatic and/or heteroaromatic primary amines to the solution; and (c) precipitating a polymer. If necessary, neutralization in a basic solution may be carried out.
