Patent number: 6869917Abstract: The present invention relates to a fully formulated lubicants comprising poly ?-olefins (PAOs), prepared from a mixed ?-olefin feed, which exhibit superior Noack volatility at low pour points, and methods for preparing the fully formulated lubricants. The fully formulated lubricants include PAOs that include mixtures of 1-decene and 1-dodecene. The PAOs may be prepared by polymerization/oligomerization using an alcohol promoted BF3 in conjunction with a combination of co-catalysts.Type: GrantFiled: August 16, 2002Date of Patent: March 22, 2005Assignee: ExxonMobil Chemical Patents Inc.Inventors: Douglas E. Deckman, Mark D. Winemiller, William L. Maxwell, David J. Baillargeon, Norman Yang, Maria Caridad B. Goze

Publication number: 20030171223Abstract: The present invention concerns friction reducers for use in lubricating oil compositions which comprise certain groups of aromatic compounds, esters, narrow mixtures of base stocks, and/or amorphous polymers such as amorphous olefin copolymers. These compositions can provide substantial reductions in the coefficient of friction and fuel economy improving benefits when admixed to lubricating oils without deleterious effects such as instability, undesirable high viscosities and deposits. In one aspect of the invention, pentaerythritol esters and optionally triol esters are added to lubricating oil compositions to provide reduced friction and improved fuel economy. In a second aspect of the invention, similar results are obtained by adding hydrocarbyl aromatics to a lubricating oil composition containing one or more of Groups II and III base stock. In a third aspect, the invention concerns a lubricating oil composition comprising an amorphous olefin copolymer and one or more of Groups II and III base stocks.Type: ApplicationFiled: January 30, 2003Publication date: September 11, 2003Inventors: Mark D.
