Mixtures of hexafluorobenzene and benzene were irradiated in liquid phase by means of a Co/sup 60/ gamma source at 20 and 218 deg C. Perfluoroheptane and various binary mixtures involving perfluoroheptane, hexafluorobenzene, benzene, and cyclohexane were also irradiated at 20 deg C. Hexafiuorobenzene resembled benzene very closely in its behavior upon radiolysis. Generally the fluorocarbonhydrocarbon mixtures evolved much more SiF/sub 4/ (indicating the formation of HF, which reacts with the glass vessel) than the pure fluorocarbon components. The polymer from hexafluorobenzene-benzene mixtures was probably rich in cyclohexadiene and cyclohexene units, resembling that from pure benzene, and its compcsition ratio exhibited a strong "alternating" tendency. The results are discussed in terms of free-radical and excitedstate mechanisms. At 218 deg C hexafluorobenzene and its mixtures with benzene showed qualitative differences from their behavior at 20 deg C, although the G values for SiF/sub 4/ and polymer remained moderate.
