Abstract
A composition containing one or more sulfur-containing compounds represented by the formula(R)(X)(R)wherein Rand Rare the same or different and are the residue of an olefin (e.g., aliphatic, aromatic or cycloaliphatic olefin) having from 4 to 40 carbon atoms, X is the residue of a thiol or polythiol,is a value from 1 to 6, andis a value from 0 to 6. The composition has a kinematic viscosity at 100° C. (Kv) from 2 to 300 cst, a kinematic viscosity at 40° C. (Kv) from 5 to 4000 cst, a viscosity index (VI) from −100 to 300, and a Noack volatility of no greater than 90 percent. A process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of solubility and dispersancy of polar additives in a lubricating oil containing the composition.
