    摘要: It now has been discovered that lubricating compositions containing (disulfido) tris (N, N-substituted dithiocarbamato) Mo(V) compounds can be enhanced by the inclusion in the composition certain polydentate ligands. Thus, the present invention comprises a major amount of an oil of lubricating viscosity and a minor, but effective, amount of an antiwear and friction reducing additive consisting essentially of (disulfido) tris (N, N-substituted dithiocarbamato) molybdenum (V) compounds and polydentate ligands and mixtures thereof.
