Abstract
Unsaturated .alpha.-olefin oligomers are topped to remove monomer and dimer and then distilled to remove a trimer fraction leaving a residue of tetramer, pentamer and higher oligomers. The trimer fraction is hydrogenated to form saturated .alpha.-olefin oligomer suitable for use as a lubricant.
