ABSTRACT:
Perfluoro(cycloaliphatic methyleneoxyalkylene) compositions are provided. These compositions comprise perfluoro(cycloaliphatic methyleneoxyalkylene) carbonyl fluoride compounds having (a) a perfluorocycloaliphatic moiety which can have up to two perfluoroalkyl substituents and a perfluoroalkylene substituent, and (b) a perfluoromethyleneoxyalkylene carbonyl fluoride radical, the methylene group of the radical being bonded to a ring carbon atom or the perfluoroalkylene substituent of the moiety and the alkylene group of the perfluoromethyleneoxyalkylene carbonyl fluoride being a perfluoro(methyl)methylene group, a perfluoroisopropyleneoxy(methyl)methylene group, or a poly(perfluoroisopropyleneoxy)perfluoro(methyl)methylene group having up to about 10 perfluoroisopropyleneoxy units. Also provided are functional derivatives of the perfluoro(cycloaliphatic methyleneoxyalkylene) carbonyl fluoride compounds and nonfunctional derivatives of the perfluoro(cycloaliphatic methyleneoxyalkylene) carbonyl fluoride compounds.
