Zusammenfassung:	A large number of trimeric and tetrameric aryl-1, 1-di-H-polyfluoroalkyl phosphonitrilates was synthesized and evaluated. Several of these products meet or approach the requirements specified in MIL-H-19457 A (Ships) for pour point, volatility, viscosity, density, spontaneous ignition temperature, and thermal and hydrolytic stability; these compounds also display excellent wear properties. Several trimeric and tetrameric arylaminopolyfluoroalkoxy phosphonitriles were prepared. The properties of a few representatives of this novel class of compounds come close to meeting the requirements for naval hydraulic fluids. Addition to ethylene oxide or glycidol to hydroxy-aryloxy- or amino-aryloxyphosphonitriles gave water soluble products which have potential for use in water base hydraulic fluids.
