ABSTRACT:
Extreme pressure additives are provided which are used in lubricant compositions. The extreme pressure additives of this invention are prepared by sulfurizing a mixture comprised of (a) 50-85% by weight of an ester of a higher fatty acid and glycerol, or a mono-lower-aliphatic ester of fatty acid, or mixtures thereof and (b) 50-15% by weight of a mono-alpha-unsaturated olefin having about 15-20 carbon atoms. The extreme pressure additives of this invention are especially useful in improving the high pressure characteristics of greases, gear oils, way lubricants and the like.
