Аннотация:Abstract Polycyclocondensations of aromatic dihydrazines 2a and 2b with 1,6‐diethoxy‐1,5‐hexadiene‐3,4‐dione ( 1a ) in m ‐cresol and those with bis(3‐chloroacryloyl)benzenes 1b and 1c in 1‐methyl‐2‐pyrrolidone (NMP) lead to aromatic polypyrazoles 3a – f having inherent viscosities up to 0,35 dl.g −1 . The polymers are soluble in polar aprotic solvents like NMP and some acidic media including m ‐cresol. Thermogravimetry shows a loss of 10 wt.‐% at ≈ 500°C both in air and nitrogen.
