Abstract: Compositions comprise first antioxidants and first additives, such as, a surface additives, performance enhancing additives and lubricant protective additives and optionally second additives and/or second antioxidants. The compositions are useful to improve lubricants, lubricant oils and other lubricant materials. The compositions and methods generally provide longer shelf lives, increased oxidative resistance, improved quality and/or enhanced performance to lubricants or lubricant oils.
Abstract: The present invention is directed toward compositions suitable for use as dielectric fluids, lubricant fluids and biodiesel fluids. Compositions described herein are obtained from a saturated, unsaturated or combinations of both monol, diol, triol or polyol acyl ester based fluid and/or a non-ester based fluid and 2,4,6-tris(di-C1-C6-alkylaminomethyl) phenol and/or the carboxylic acid salt of 2,4,6-tris(di-C1-C6-alkylaminomethyl) phenol. These compositions demonstrate improved oxidative stability and/or hydrolytic stability at higher use temperatures.
Abstract: Hindered amines useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials, and lubricating oil compositions containing such compounds.

Abstract: A magnetic recording medium comprising a lubricant film comprising a photosynthesized lubricant having a single phase composition of at least a lubricant moiety and an additive moiety is disclosed.
Abstract: The present invention relates to a novel process for the production of fuel and lubricant additives useful as dispersants and multifunctional viscosity modifiers wherein a dihydroxyaromatic compound is alkylated with an olefinic polymer and then aminated in such a manner as to oxidize the hydroxyl moieties of the dihydroxyaromatic compound to carbonyl groups.
