  • Dilute process for the polymerization of non-ethylene .alpha.-olefin homopolymers and copolymers using metallocene catalyst systems
    Patent number: 5859159
    Abstract: An improved process for the homopolymerization and copolymerization of .alpha.-olefins utilizing highly dilute .alpha.-olefin feedstreams to effect high conversions and catalyst efficiencies in the production of non-ethylene copolymers. The instant invention is particularly adaptable to polymerizing the .alpha.-olefin content of commercially available refinery feedstreams such as Raffinate-2.
    Type: Grant
    Filed: March 14, 1997
    Date of Patent: January 12, 1999
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Albert Rossi, Salvatore Rea, Jon E. Stanat, Linda K. Wright, Kenneth L. Kaufman, Jeffrey W. Frederick, Robert Martin Koros, Harold Wilbur Margo
