Novel Benzobistriazolo phenanthroline Polymers.

Abstract

Novel, high molecular weight benzobistriazolo phenanthroline polymers were prepared by the polycondensation of 1,4,5,8-naphthalene tetracarboxylic acid with iso- or tere-phthaldihydrazidine dihydrochloride in polyphosphoric acid. Inherent viscosities in the range of 1.33 to 2.51 were recorded. Tough, transparent films of these polymers could be cast from methane sulfonic acid. Onset of polymer breakdown during thermogravimetric analysis in an air atmosphere occurred at 460C.
