    摘要: 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%.

    摘要: Polyolefins made in accordance with the present invention are produced by polymerizing an unsaturated olefin or combination of unsaturated olefins to produce an unsaturated polyolefin, isomerizing the unsaturated polyolefin in the presence of an acid catalyst under conditions to produce a substantially unsaturated-isomerized polyolefin, and hydrogenating the unsaturated-isomerized polyolefin to produce a saturated isomerized polyolefin. A lube oil comprising the inventive saturated isomerized polyolefin is also disclosed.
