Abstract: This invention relates to the use of olefin mixtures containing 1-hexene/1-decene/1-dodecene and, additionally, 1-octene or 1-decene to produce high viscosity polyalphaolefins (PAOs) having a viscosity of from about 40 cSt to about 100 cSt at 100° C. (ASTM D-445) and a number average molecular weight of between about 1200 to about 4000, particularly useful as lubricant base stocks.

Abstract: Polyolefins made in accordance with the present invention are produced by polymerizing an unsaturated olefin or combination of unsaturated olefins to produce an unsaturated polyolefin, isomerizing the unsaturated polyolefin in the presence of an acid catalyst under conditions to produce a substantially unsaturated-isomerized polyolefin, and hydrogenating the unsaturated-isomerized polyolefin to produce a saturated isomerized polyolefin. A lube oil comprising the inventive saturated isomerized polyolefin is also disclosed.

Abstract: The invention relates to a method of making a PAO characterized by a low viscosity, low Noack volatility, and excellent cold temperature properties, using a promoter system comprising an alcohol and an ester. The products comprise trimers obtained by fractionating a hydrogenated bottoms product from an oligomerization process using said promoter system.
