A liquid polymer suitable for use as a lubricant base oil is produced by polymerizing ethylene and at least one alpha-olefin using a metallocene catalyst to provide a polymer which is then isomerized and hydrogenated to produce the liquid polymer.

Synthetic lubricant composition and process

A synthetic lubricant base stock is provided having a kinematic viscosity at 100&#xb0; C. of from 5 to about 300 cS and a VI greater than 100. The base stock comprises random co-oligomers of an alpha olefin or mixtures thereof and an olefinic substituted aromatic compound which co-oligomers are prepared in the presence of a Friedel-Crafts catalyst.
