FREE-RADICAL AND ION CHEMISTRY OF FLUORO DERIVATIVES - THE MECHANISM OF GAMMA-RADIOLYSIS OF PERFLUOROPOLYPROPENE AND PERFLUOROPOLYTRIMETHYLENE OXIDES

The radiation chemistry of perfluoropolypropene and perfluoropolytrime thylene oxides has been investigated by ESR spectroscopy of the interm ediate free radicals and by NMR spectroscopic detection of the major c hanges occurring in the structure of the oligomers. The major radiolyt ic products have been related to C-C and C-O bond scissions and to a m inor participation of C-F bond cleavage. The results have been rationa lized in terms of ionic and free-radical reactions stemming from the f ormation of primary ether cation-radicals.
