    摘要: 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 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.

    摘要: Disclosed herein is a method of making a PAO using tetradecene and particularly mixtures comprising 1-hexene, 1-decene, 1-dodecene, and 1-tetradecene, characterized by a low viscosity and excellent cold temperature properties, using a promoter system comprising an alcohol and an ester. In embodiments, the product has properties similar to those obtainable using a feed of solely 1-decene.
