FLUORINATED POLYMERS AND FLUIDS.
Abstract
Poly(tetrafluoro-m-phenylene pyromellitimide) has been fabricated in the form of laminate with glass cloth, as filled and unfilled sintered material, and as solid foam. Poly(tetrafluoro-m/p-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 poly(m-phenylene pyromellitimide), poly(m-phenylene difluoropyromellitimide), and poly(tetrafluoro-m-phenylene difluoropyromellitimide). Poly(tetrafluoro-m-phenylene carbonate) was prepared and had thermo-oxidative stability of the same order as that of poly(m-phenylene carbonate). Reactions of 4-hydroxy-2,3,5,6-tetrafluorophenyl bis(trifluoromethyl) 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.
