ABSTRACT:
New perfluoroalkanes and haloperfluoroalkanes, having low melting point and high thermal and chemical stability, constituted by preferably branched perfluorinated and haloperfluorinated chains, obtained by starting from precursors containing two halogen atoms equal to or different from each other, one of them necessarily being an iodine atom, which are reacted with C.sub.3 F.sub.6 and possibly subsequently halogenated with either fluorine or chlorine or bromine.
