  • Patent number: 10351488
    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.
