ABSTRACT:
Perfluoroethers having a spherical shape are described. The perfluoroethers can be represented by the formula ##STR1## wherein R.sub.f1, R.sub.f2, R.sub.f3 and R.sub.f4 are the same or different and are selected from short, straight or branched chain perfluoroalkyl or perfluoroether groups. The perfluoropolyethers are designed to act like "molecular ball bearings" and have high thermal stability and lubrication properties. They are useful as stable fluids, heat transfer fluids, vapor phase soldering fluids and oxygen carriers.
