The present invention relates to poly &#x3b1;-olefins (PAO's) which exhibit superior Noack volatility at low pour points. Mixtures of 1-decene and 1-dodecene are polymerized using an alcohol promoted BFin conjunction with a combination of cocatalysts. The reaction mixture is distilled to remove the unreacted monomeric and dimeric species. The resulting product is then hydrogenated to saturate the oliogomers to provide a hydrogenated product which has a viscosity of 5 cSt. This product is distilled to provide PAO's of varying viscosity grades. The 4 cSt PAO is comprised mostly of trimers and tetramers while the 6 cSt product is comprised of trimers, tetramers, and pentamers.

Low Noack volatility poly &#x3b1;-olefins

The present invention relates to a fully formulated lubicants comprising poly &#x3b1;-olefins (PAOs), prepared from a mixed &#x3b1;-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 BFin conjunction with a combination of co-catalysts.

Functional fluid lubricant using low Noack volatility base stock fluids

The present invention relates to poly &agr;-olefins (PAO's) which exhibit superior Noack volatility at low pour points. Mixtures of 1-decene and 1-dodecene are polymerized using an alcohol promoted BF in conjunction with a combination of cocatalysts. The reaction mixture is distilled to remove the unreacted monomeric and dimeric species. The resulting product is then hydrogenated to saturate the oliogomers to provide a hydrogenated product which has a viscosity of 5 cSt. This product is distilled to provide PAO's of varying viscosity grades. The 4 cSt PAO is comprised mostly of trimers and tetramers while the 6 cSt product is comprised of trimers, tetramers, and pentamers.
