New poly(imide-pyridazine-amide)s have been synthesized by the solution polycondensation of aromatic diamines containing preformed pyridazine rings with diacid chlorides which incorporate both imide and hexafluoroisopropylidene units. Solubility, thermal stablhty and electro-insulating properties of these compounds are discussed and compared with those of fluorinated poly(imide-amide)s which do not contain pyridazine rings, and also with those of other related heterocyclic polymers that have been previously reported
