Abstract
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.
