The synthesis of a new bis-sydnone N,N-hexamethylene-bis-sydnone has been accomplished by the cyanomethylation of hexamethylenediamine followed by nitrosation and dehydration. The polymerization of N,N-hexamethylene-bis-sydnone with p-diethynylbenzene and m-diethynylbenzene yielded poly 1,1-hexamethylene-3,3-p-phenylenedi-pyrazole and poly 1,1-hexamethylene-3,3 -m-phenylenedi-pyrazole respectively. The homopolymerization of 2,2-diphenyl-5,5-p-phenyleneditetrazole has afforded poly 1,4-dipheynl-3,6-p-phenylene1,4-dihydro-1,2,4,5-tetrazine. A series of polymerizations with 2,2-diphenyl-5,5-p-phenyleneditetrazole in which the monomer balance was varied has been carried out. Author
