Abstract: Unsaturated polyalpha-olefin (uPAO) materials comprising a mixture of vinylidene olefins, 1,2-di-substituted vinylene olefins, and tri-substituted vinylene olefins. The unsaturated PAO material can be made from alpha-olefin monomer(s) in the presence of a metallocene-compound-based catalyst system. The unsaturated PAO material can be used as intermediate material for making PAO materials having functional groups.

Abstract: The present disclosure relates to processes to produce a poly alpha-olefin (PAO) composition. In some embodiments, a process includes introducing a first C6-C32 alpha-olefin, a second C6-C32 alpha-olefin different than the first C6-C32 alpha-olefin, and a first catalyst system comprising an activator and a metallocene compound into a first reactor, wherein a molar ratio of the first C6-C32 alpha-olefin to the second C6-C32 alpha-olefin is from about 1:5 to about 5:1, by total moles of the first and second C6-C32 alpha-olefin; obtaining a first effluent including a PAO dimer; introducing the first effluent, a third C6-C32 alpha-olefin, and a second catalyst system to an oligomerization unit, wherein the third C6-C32 alpha-olefin is the same or different than the first C6-C32 alpha-olefin and/or second C6-C32 alpha-olefin; obtaining a second effluent; and hydrogenating the second effluent to form the PAO composition.

Abstract: The present disclosure generally relates to process to produce a poly alpha-olefin (PAO), comprising: a) introducing a first alpha-olefin to a first catalyst system comprising non-aromatic hydrocarbon soluble activator and a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under first reactor conditions, wherein the first alpha-olefin is preferably introduced to the reactor at a flow rate of about 100 g/hr or more, to form a first reactor effluent comprising PAO (such as at least 60 wt % of PAO dimer and 40 wt % or less of higher oligomers, where the higher oligomers are oligomers that have a degree of polymerization of 3 or more); and b) introducing the first reactor effluent and a second alpha-olefin to a second catalyst composition comprising an acid catalyst, such as BF3, in a second reactor to form a second reactor effluent comprising PAO trimer.

Abstract: In at least one embodiment, a process to produce a poly alpha-olefin (PAO) includes introducing a first alpha-olefin to a first catalyst system comprising activator and a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under first reactor conditions to form a first reactor effluent. The first alpha-olefin is introduced to the reactor at a flow rate of about 100 g/hr or more. The first reactor effluent includes at least 60 wt % of PAO dimer and 40 wt % or less of higher oligomers, where the higher oligomers are oligomers that have a degree of polymerization of 3 or more. The process includes introducing the first reactor effluent and a second alpha-olefin to a second catalyst composition including an acid catalyst in a second reactor to form a second reactor effluent comprising PAO trimer.
