Abstract: A composition useful as a lubricant or cutting fluid includes: an oil of lubricant viscosity; the adduct of a polycarboxylic compound such as hydrocarbyl-substituted succinic anhydride with a hydroxy-containing amine; an active sulphur-containing organic compound such as a sulfurized olefin; and an alkali metal- or alkaline earth metal-containing compound. The composition exhibits reduced hydrogen sulfide generation.

Abstract: This invention relates to a lubricating composition comprising at least about 30% by weight of at least one mineral oil, having a kinematic viscosity of less than about 8 cSt at 100 DEG C, (A) from about 5% to about 30% by weight at least one polymer having a Mw less than about 10,000, and (B) from about 2% to about 12% by weight of a polymer having a Mw greater than about 15,000, wherein the lubricating composition has a shear loss of less than about 15% in the 20 hour taper bearing shear test. The invention also relates to concentrates used in preparing shear stable lubricating compositions. The present combination of components provides good low and high temperature properties to mineral oils, even at high treat levels. These lubricants have good shear stability and in one aspect have improved oxidation resistance.

Abstract: Esta invencion se refiere a una composicion lubricante que comprende al menos aproximadamente 30% en peso de al menos un aceite mineral, que tiene una viscosidad cinemática de menos de aproximadamente 8 cSt a 100 degree C, (A) de aproximadamente 5% a aproximadamente 30% en peso de al menos un polímero que tiene un Mw de menos de aproximadamente 10.000, y (B) de aproximadamente 2% a aproximadamente 12% en peso de un polímero que tiene un Mw superior a aproximadamente 15.000, donde la composicion lubricante tiene una pérdida al cizallamiento de al menos aproximadamente 15% en el ensayo de cizallamiento de cojinete de rodillos conicos de 20 horas. La invencion se refiere también a concentrados utilizados en la preparacion de composiciones lubricantes estables al cizallamiento. La presente combinacion de componentes proporciona buenas propiedades a bajas y altas temperaturas a aceites minerales, incluso a altos niveles de tratamiento. Estos lubricantes tienen una buena estabilidad al cizallamiento y en un aspecto tienen resistencia mejorada a la oxidacion.
