ABSTRACT:
Compositions useful as lubricants and functional fluids comprise an oleaginous liquid of lubricating viscosity, typically a mineral oil, and an oxygen-, sulfur- or 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.
