| Notes: |
By the interaction of linear or branched bis(β-diketones) and dihydrazides of dicarboxylic acids or dihydrazines unknown high molecular compounds with pyrazole rings in the chain have been prepared. Polypyrazoles of the second type (with a free NH-group in the pyrazole ring) were prepared by the interaction of bisdiazoalkanes and diacetylenes. Some features of the polycyclization reaction as well as the structure and properties of polymers obtained are discussed.
