Abstract:

Work on the 1,2,4-triazole polymer system, in which these heterocyclic groups are connected by perfluoroalkylene chains, included assignment of structure to cyclic product from perfluoroglutaronitrile and N2H4, opening of this cyclic product with polymerization to polyN2-imidoyl perfluoroglutar hydrazidine, and synthesis of polyperfluoropropylene- 1,2,4- triazole both from the polyimidoyl hydrazidine and directly from the original cyclic monomer. Other routes to this type of polymer were considered. Preparation of 2,6-bis perfluoroethyl-4-hydroxy- 1.3.5-triazine was completed. Further study of the 2-perfluoroalkyl- 5-hydroxy-1,3,4- oxadiazoles as possible monomers for polymerization was carried out. Synthesis of a perfluoroalkyl- substituted heterocycle with an electron-donating group attached to a heteroatom, 3.5-bisperfluoroalkyl- 4-amino-1,2,4,4H- triazole, was completed and the structure was verified.
