A benzobistriazolo phenanthroline polymer was prepared by the polycondensation of 2,6-pyridinediyldihydrazidine with 1,4,5,8-naphthalene tetracarboxylic acid or 1,4,5,8-naphthalene tetracarboxylic dianhydride in polyphosphoric acid. Inherent viscosities in the range of 0.25-0.87 dl.g. were recorded. Polymer structure was established by elemental and infrared analysis. The polymer was a reddish-brown powder soluble in sulfuric-or methane sulfonic- acid. Onset of breakdown during thermogravimetric analysis in a nitrogen atmosphere occurred at 475C.
