The synthesis of a new tetrazole double dipole, 2,2-diphenyl-5,5-m-phenyleneditetrazole, has been accomplished. The reaction of this bistetrazole with phenylacetylene yielded the model compound 1,1,5,5-tetraphenyl-3,3-m-phenylenedipyrazole. The attempted polymerization reaction of 2,2-diphenyl-5,5-p-phenyleneditetrazole with terephthalonitrile in either acetic acid or nitrobenzene has been carried out, but no polymer was obtained. A monomer balance study was carried out on the polymerization reaction of 2,2-diphenyl-5,5-p-phenyleneditetrazole with tetrafluoroterephthalonitrile for the formation of poly1,1-diphenyl-3,3-p-phenylene-5,5-tetrafluoro-p-phenylene -ditriazole.
