  • Highly branched, low molecular weight polyolefins and methods for their production
    Patent number: 11780941
    Abstract: Low molecular weight, highly branched polyolefins are provided. Also provided are catalyst-mediated methods of making the low molecular weight, highly branched polyolefins and a catalyst system for carrying out the methods. The catalyst system is a homogeneous catalytic system that includes a single-site organozirconium complex and hydrocarbon-soluble perfluoroarylborate co-catalyst that is highly active for the oligomerization of olefin monomers in non-polar media.
    Type: Grant
    Filed: January 12, 2022
    Date of Patent: October 10, 2023
    Assignee: Northwestern University
    Inventors: Tobin Jay Marks, Yanshan Gao, Tracy L. Lohr, Qian Wang, Yip-Wah Chung, David B. Pickens, III
