Abstract
The present invention relates to a fully formulated lubicants comprising poly α-olefins (PAOs), prepared from a mixed α-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.
