摘要： The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated and functionalized. The dispersant substances include compositions including a copolymer of two different conjugated dienes, a copolymer of a p-alkylstyrene and a conjugated diene, or a homopolymer of a conjugated diene. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.

摘要： The invention relates to lubricants which contain a phosphorus to nitrogen ratio of ≧1.0 and a sulfur content of >1.4 wt. %. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or “green gears”, during the break-in phase.
