摘要: Poly alpha olefins (PAOs) are characterized by very low viscosity and excellent Noack volatility. A preferred process for synthesizing said PAOs involves first oligomerizing low molecular weight linear alpha olefins in the presence of a single site catalyst at high temperatures without adding hydrogen and then subsequently oligomerizing at least a portion of the product from the first step in the presence of an oligomerization catalyst.

摘要: The invention relates to a method of making a PAO characterized by a low viscosity, low Noack volatility, and excellent cold temperature properties, using a promoter system comprising an alcohol and an ester. The products comprise trimers obtained by fractionating a hydrogenated bottoms product from an oligomerization process using said promoter system.
