Hydrofluoropolyethers: a new “friendly” generation of fluorinated fluids

In this paper, some physico-chemical properties of a novel class of α–ω hydrofluoropolyethers (HFPEs) having terminal hydrogen atoms are presented and compared with those of similar perfluorinated structures. The effect of –CF2H end groups has been studied for the lower members of this family and its group contributions, determined for some physico-chemical properties, have been calculated and can be used to predict properties of new structures.
