New low-molecular-weight perfluoroalkylethers (PFAE's) synthesized by direct fluorination in experimental study. Correlated viscosity and oxidation characteristics of PFAE's with structures to evaluate suitability as high-temperature lubricants and hydraulic fluids. Direct fluorination process attractive because it often involves single-step reaction and uses cheap starting materials. Versatile: produces highly branched ethers as well as polyethers containing more than two sequential carbon atoms in polymer chains. Such molecules cannot be made by conventional techniques.
