HIGH TEMPERATURE POLYMERS FROM 1,3-DIPOLAR ADDITION REACTIONS.

Abstract

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 poly(1,1'-diphenyl-3,3'-p-phenylene-5,5'-(tetrafluoro-p-phenylene) -ditriazole).
