ABSTRACT:
A process for preparing a concentrate of a polyalpha-olefin in a hydrotreated lubricating oil base stock by conditioning the base stock in the presence of hydrogen and a Ziegler-Natta type catalyst and then polymerizing an alpha-olefin in the conditioned, hydrotreated lubricating oil base stock as the reaction medium. The resulting concentrate of the polyalpha-olefin dissolved in the hydrotreated lubricating oil base stock is useful as an additive in preparing multiviscosity graded motor oils.
