| abstract |
The present invention relates to a polyoxadiazole complex made by a condensation polymerization reaction of an AA (hydrazine and / or derivative thereof) monomer and a BB (dicarboxylic acid and / or derivative thereof) monomer and a filler in polyphosphoric acid, preferably a direct condensation polymerization reaction. As a method of preparing, the method comprises the following steps:n n n a) the filler is functionalized in polyphosphoric acid, preferably under a gaseous atmosphere, by heating the mixture,n n n b) hydrazine and / or its derivatives and at least one dicarboxylic acid and / or its derivatives are mixed into a mixture and solution from step a),n n n c) preferably in an inert atmosphere, the solution from step b) is heated, andn n n d) polyoxadiazole complex is precipitated in solution, in particular neutralizedn n n Has The present invention also relates to the use of polyoxadiazole complexes and polyoxadiazole complexes. |
