PROCESS FOR CO-REACTING POLY(ISOBUTYLENE) AND LINEAR OLEFINS TO PREPARE SYNTHETIC LUBRICANT BASE STOCKS HAVING IMPROVED PROPERTIES

摘要

(D# 81,017-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 montmorillonite clay catalysts. When a mixture of poly(isobutylene) and long-chain linear olefin, in which up to about 10 wt.% of the mixture is poly(isobutylene), is co-reacted in the presence of these catalysts, a synthetic lubricant base stock having a high viscosity and a high viscosity index is prepared.
