Perfluoro(alkoxycycloalkane)carbonyl fluoride compositions and their use |
摘要 |
This invention provides perfluoro(alkoxycycloalkane) carbonyl fluoride compounds wherein, pendant from the fluorinated ring, are from 2 to 5 perfluoroalkoxy groups having from 1 to 4, preferably 1 to 2, carbon atoms with the proviso that when one or more of the perfluoroalkoxy groups contain from 3 to 4 carbon atoms, there are no more than 3 pendant groups. In yet another aspect, this invention provides aqueous film-forming foam (AFFF) compositions comprising one or more perfluoro(alkoxycycloalkane) carbonyl group-containing surfactants and one or more water-soluble fluorine-free surfactants selected from the group consisting of nonionic hydrocarbon-containing surfactants with a hydrophilic-lipophilic balance (HLB) value greater than or equal to about 10 and ionic hydrocarbon-containing surfactants having a carbon chain length containing inclusively from about 6 to about 10 carbon atoms./!
