ABSTRACT:
Liquid polyolefin oil having a kinematic viscosity of about 500 centistokes or more at 100.degree. F, a high viscosity index, a good shearing stability and a low pour point can be prepared by polymerizing an olefin having 6 or more carbon atoms in the presence of a catalyst mixture of (a) a dicarbonyl compound selected from a group consisting of acyclic or cyclic diketones and ketoesters and (b) an aluminum halide in an amount of 0.7 - 5 mole per one carbonyl group or ester bond of said dicarbonyl compound. Said catalyst mixture may contain an alkyl halide.
