Abstract
The present invention relates to poly alpha-olefins (PAO's) which exhibit superior Noack volatility at low pour points. The poly alpha-olefin is prepared from an olefin feed comprised of a blend of octene, decene, and dodecene, the feed comprising at least 10 weight % octene and at least 30 weight % dodecene. The process includes both synthesis and distillation of the olefin and oligomerization olefin. The oligomerized olefin feed yields at least 50% low viscosity PAO having a nominal viscosity at 100° C. of about 4 cSt.
