A novel Diels–Alder polymerization system was developed, using an azodicarbonyl compound as the dienophile. A bis(azodicarbonyl) monomer was prepared by quantitative oxidation of bis(diacylhydrazine) with tBuOCl in the presence of pyridine. Diels–Alder polymerization was carried out with a bisdiene monomer, using AgOTf as the catalyst. High thermalstability of the polymer is characteristic for the
