摘要
Compositions are provided which are aliphatic sulfurized esters of olefinic mono- or dicarboxylic acids which do not contain any allylic hydrogen atoms. Synergistic mixtures of esters sulfurized with sulfur and with sulfur monochloride and sulfur dichloride are provided. Also provided are lubricating oil compositions comprising (A) a major amount of an oil of lubricating viscosity, and (B) an amount effective to impart extreme-pressure and/or antiwear lubricating properties to said oil of these sulfurized esters.
