  • Patent number: 5846516
    Abstract: Perfluoroalkylated amphiphilic phosphorus compounds, corresponding to the formulae: ##STR1## wherein V is O or S;R.sup.1, R.sup.2 and R.sup.3 are H or substituted or unsubstituted perfluoroalkylated or hydrocarbon radicals;provided thatR.sup.1, R.sup.2 or R.sup.3 is a perfluoroalkylated radical; and Y and Z are radicals which can bear a part derived from a sugar, a polyol, or a hydrophilic polymer such as polyethyleneglycol, a perfluoroalkylated part or a part derived from a pharmaceutically active molecule, and method for their preparation and use. These compounds can be included in preparations, emulsions, dispersions, gels, microemulsions, notably for biomedical uses.

  • Patent number: 5582813
    Abstract: The present invention relates to nonterminally iodinated fluorinated compositions. The compositions, including, dispersions, emulsions, microemulsions, and gels are useful for biomedical applications, particularly radiography and scintigraphy. The compounds used in the invention preferably have the following general formula:R.sub.F CH.dbd.CIR.sup.1wherein,R.sub.F is a linear, branched, or cyclic first fluorocarbon radical, having 2 to 12 carbon atoms in which 50 to 100% of the hydrogen atoms have been replaced by fluorine atoms; andR.sup.1 is selected from the group consisting of a second fluorocarbon radical and a hydrocarbon radical, wherein,the second fluorocarbon radical is linear, branched, or cyclic, having 2 to 12 carbon atoms in which 50 to 100% of the hydrogen atoms have been replaced by fluorine atoms; andthe hydrocarbon radical is linear, branched, or cyclic, having 2 to 14 carbon atoms.

  • Patent number: 4985550
    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.
