Abstract:
1. A functionalized polytriazole polymer obtained by a method 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 and adding at least one primary amine to the solution to form polytriazoles, wherein said primary amine is selected from a group consisting of aromatic primary amines and heteroaromatic primary amines; and c) precipitating a polymer from the solution, wherein the functionalized polymer is soluble in aprotic polar solvents and in strong acids, wherein a molar ratio S/C of sulfur to carbon is between 0.018 and 0.400.
