  • Process for preparing peroxide perfluoropolyethers
    Patent number: 5149842
    Abstract: A process is disclosed for preparing peroxidic perfluoropolyethers comprising perfluoroalkylenoxy units having at least two carbon atoms, characterized in that one or more perfluoroolefins, except tetrafluoroethylene used alone, are reacted with oxygen in the liquid phase at a temperature not exceeding 50.degree. C. and in the presence of one or more compounds having one or more F-X bonds, in which X is selected from the group consisting of F, O and Cl.

  • Perfluoroalkenes and fluorination products thereof
    Patent number: 5124420
    Abstract: The present invention relates to the synthesis of new terminal olefins, perfluoro 2,4-dimethyl 3-ethylpentene and perfluoro 2-isopropyl 3,3-dimethyl butene, and to the subsequent fluorination thereof in order to obtain highly branched perfluoroalkanes, capable of providing perfluoroalkyl radicals, which are utilizable as initiators for the polymerization of ethylenically unsaturated monomers.
