<p>Title: LUBRICANTS AND FUNCTIONAL FLUIDS CONTAINING POLYFUNCTIONAL NITRILES Inventor: Donald Irvin Hoke Compositions useful as lubricants and functional fluids comprise an oleaginous liquid of lubricating viscosity, typically a mineral oil, and an oxygen-, sulfuror nitrogen-containing polyfunctional nitrile. The preferred nitriles are cyanoethylation products of alcohols, mercaptans and amines, and especially of alcohols. The polyfunctional nitrile serves as a seal swelling agent and/or demulsifier.</p> |
