  • Polymerization process
    Patent number: 6521724
    Abstract: Processes for the polymerization of olefins in which late transition metal complexes, such as nickel, iron, cobalt and palladium complexes, are used as a polymerization catalyst have improved polymer productivity when oxidizing agents are present during at least a portion of the polymerization. The polymers produced are useful as elastomers, for packaging films, and molding resins.
    Type: Grant
    Filed: March 7, 2001
    Date of Patent: February 18, 2003
    Assignees: E. I. du Pont de Nemours and Company, Basell Technology Company B.V.
    Inventors: Samuel David Arthur, Mark F. Teasley, Dewey Lynn Kerbow, Ofelia Fusco, Tiziano Dall 'Occo, Giampiero Morini
  • Process for the preparation of ethylene polymers
    Publication number: 20020198339
    Abstract: Ethylene based polymers having high molecular weights can be obtained in high yields at temperatures of industrial interest, by carrying out the polymerization reaction in the presence of catalysts comprising single carbon bridged metallocenes, which has a particular ligand system containing a heteroatom.
