Notes:
The cyclopolycondensation of linear bis-β-diketones with aromatic dihydrazines in dimethyl sulfoxide at 100-150°C produced a series of aromatic polypyrazoles with inherent viscosities up to 0.6 dL/g. All the polymers were highly soluble in a wide range of solvents, which included tetrahydrofuran and chloroform. The polypyrazoles showed excellent thermal stability with 10% weight loss at 410-490°C in air and nitrogen atmosphere.
