Abstract
A process for the preparation of oligomeric poly alpha-olefins includes oligomerizing low molecular weight PAO oligomer in the presence of a Lewis acid catalyst such as promoted aluminum trichloride or boron trifluoride under oligomerization conditions. The low molecular weight PAO oligomers used as a feed or feed component of the present process are the light olefinic by-product fractions including the dimers and light fractions from the metallocene-catalyzed PAO oligomerization process which are characterized by a molecular weight of 150 to 600 and a terminal olefin (vinylidene) content of at least 25%.
