ABSTRACT (D# 80,944-F) A process is disclosed for preparing synthetic lubricant base stocks having improved properties. Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefins using certain acidic calcium montmorillonite clay catalysts. When a mixture of 1,3-di-isopropenyl benzene and long- chain alpha-olefin is used, in which up to about 20 wt.% of the mixture comprises 1,3-di-isopropenyl benzene, and the co-oligomers prepared therefrom are hydrogenated, a synthetic lubricant base stock having a lower pour point and a higher viscosity is prepared.
