<P>PROBLEM TO BE SOLVED: To provide a method for the producing a functionalized polytriazole polymer. <P>SOLUTION: The method for producing the functionalized polytriazole polymer, particularly a poly(1,2,4-triazole)-polymer, comprises 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 derivative 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 an aromatic and/or heteroaromatic primary amine to the solution, and (c) precipitating a polymer, if necessary neutralizing it in a basic solution. <P>COPYRIGHT: (C)2008,JPO&INPIT |
