THERMALLY STABLE PERFLUORINATED POLYMERS.
Abstract
Ring closure of the N (perfluoroacylimidoyl) perfluoroalkyl amidine by acylation with perfluoroacyl chloride was apparently hindered by formation of a hydrochloride salt of the acylated product; formation and acylation of the silver salt of the imidoyl amidine yielded the desired triazine quantitatively. The reaction of perfluoroadiphydrazidine with perfluoroadiponitrile produced the intermediate polyimidoylhydrazidine as a step in a perfluoroalkyltriazole polymer synthesis. Reaction of perfluoroglutaronitrile with N2H4 produced a cyclic compound which may be useful as a single monomer for formation of the intermediate polymer. The 5-perfluoroalkyl tetrazoles were useful intermediates for the synthesis of the perfluoroalkyl substituted 1,2,4-triazoles and pyrazoles. From pyrolysis of the tetrazoles, 3,6-ais(perfluoroalkyl)1,2-dihydro-1,2,4,5-tetrazine was isolated, and perfluorobutyrnitrilimine was separated and identified. (Author)
