Abstract
Compounds having a polyhydroxylated hydrophilic moiety, a highly fluorinated moiety and a functional junction group linking said moieties together, wherein said hydrophilic moiety is derived from a polyol or an aminopolyol, and wherein said highly fluorinated moiety consists of a fluorocarbon group wherein at lest 50% of the atoms bonded to the carbon skeleton are fluorine atoms, the other atoms bonded to the carbon skeleton being hydrogen, chlorine or bromine atoms, said highly fluorinated moiety containing at least 4 fluorine atoms; as well as the internal ethers and ketals thereof; process for their preparation; and a compositions containing said compounds as surfactants, together with non polar compounds, for use as gas carriers.
