Abstract:

Polytetrafluoro-m-phenylene pyromellitimide has been fabricated in the form of laminate with glass cloth, as filled and unfilled sintered material, and as solid foam. Polytetrafluoro-mp-phenylene pyromellitimide has been fabricated in the form of laminate with glass cloth. The flexural strength and modulus of the laminated and sintered polyimides have been investigated. Thermo-oxidative stability of a high order was observed, and thermo-oxidative comparisons were made with polym-phenylene pyromellitimide, polym-phenylene difluoropyromellitimide, and polytetrafluoro-m-phenylene difluoropyromellitimide. Polytetrafluoro-m-phenylene carbonate was prepared and had thermo-oxidative stability of the same order as that of polym-phenylene carbonate. Reactions of 4-hydroxy-2,3,5,6-tetrafluorophenyl bistrifluoromethyl carbinol were investigated. The arylation of decafluorobiphenyl by aryl sulphonyl chlorides was also investigated. The syntheses of the intermediates are given. Syntheses are described for substituted perfluoro-biphenyls, oxydifluoromethylene-linked perfluoro-biphenyls, and perfluoro-alpha, omega-aryloxyalkanes.
