Normally liquid peroxidic poly(perfluorooxyalkylene) compositions comprising a mixture of peroxidic poly-(perfluorooxyalkylene) compounds, derivatives of the poly(perfluorooxyalkylene) compositions comprising a mixture of non-peroxidic polyfluoropolyether compounds, and derivatives of the polyfluoropolyether compositions comprising functional and non-functional derivatives of the polyfluoropolyether compositions are provided. Each peroxidic poly(perfluorooxyalkylene) compound comprises a backbone of randomly distributed perfluorooxyalkylene units, represented by the formulas -CF 2 0-, - C FO-, and -CF 2 C FO, and -0-, which when bonded to an -0-of any of the perfluorooxyalkylene units, forms a peroxy group, -0-0-, which imparts the peroxidic characteristics to the material, and backbone-pendant perfluoroalkoxy groups or perfluoroalkoxy groups substituted with one or more ether oxygen atoms, the terminal ether oxygen atoms of which are bonded to carbon atoms of then backbone units. |
