ABSTRACT:
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 ##STR1## which when bonded to an --O-- of any of the perfluorooxyalkylene units, forms a peroxy group, --O--O--, 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 the ##STR2## backbone units.
