  • Olefin polymerization process
    Patent number: 6794468
    Abstract: A process for polymerizing olefins is disclosed. The process combines a bridged indenoindolyl organometallic complex and an activator with a support material in the presence of an aromatic solvent. The supported catalyst containing the aromatic solvent is used to polymerize an olefin in the presence of hydrogen. Polyolefins from the process have improved flow properties.
