  • Low Noack volatility poly ?-olefins
    Patent number: 6949688
    Abstract: The present invention relates to poly ?-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 BF3 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.

  • Functional fluid lubricant using low Noack volatility base stock fluids
    Patent number: 6869917
    Abstract: 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.
