For example, compositions, useful as additives to libricants (e.g., components of traction fluids), are produced by oxonolysis of polyolefins, particularly of polyisobutylene oligimers containing at least one pair of maximally crowded geminal methyl groups. For example, ozonolysis of the novel polyisobutylenes can produce oxygenated derivatives (ketones, esters, acids, aldehydes, alcohols, etc.) which are useful as components of traction fluids. Blends of the ketones or of mixtures of the acids and ketones with a base oil (e.g., a paraffinic lube, naphthenic lube, a hydrogenated naphthenic or paraffinic lube, polyolefins or hydrogenated polyolefins) are especially useful as traction fluids or as a lubricant for a friction drive or a limited slip differential. Other polar compounds, useful as additives to lubricants or other mineral oil products (e.g., rubber process oils) can be obtained by conversion of polyisobutylene oligimers to polar compounds containing such functional groups as amine, imine, thioketone, amide, thioester, phosphate esters of the alcohols, ether, oxime, acyl halide, acyl hydrazide, chloride, bromide and maleic anhydride adducts. Salts of the carboxylic acids can also be useful as lubricant additives. A tin complex can also be made which has antiwear properties.,下面是Lubricant comprising gem-structured organo compound专利的具体信息内容。
