  • Patent number: 7230056
    Abstract: A two-step catalyst preparation method is disclosed. First, a support is combined with an indenoindolyl Group 3-10 metal complex and a first activator comprising an alkyl alumoxane to give a supported complex. The supported complex is subsequently combined with a second activator comprising an ionic borate to produce a borate-treated supported complex. Activating indenoindolyl metal complexes in this sequence surprisingly provides an exceptional activity boost compared with other ways of activating them with either or both types of activators.

  • Patent number: 7220695
    Abstract: This invention relates to supported activators comprising the product of the combination of an ion-exchange layered silicate, an organoaluminum compound, and a heterocyclic compound, which may be substituted or unsubstituted. This invention further relates to catalyst systems comprising catalyst compounds and such activators, as well as processes to polymerize unsaturated monomers using the supported activators. For the purposes of this patent specification and the claims thereto, the term “activator” is used interchangeably with the term “co-catalyst”, the term “catalyst” refers to a metal compound that when combined with an activator polymerizes olefins, and the term “catalyst system” refers to the combination of a catalyst and an activator with or without a support. The terms “support” or “carrier”, for purposes of this patent specification, are used interchangeably and are any ion-exchange layered silicates.

  • Patent number: 7208441
    Abstract: A copolymer of ethylene and a higher alpha olefin, preferably 1-hexene, can be produced using an activated chromium containing catalyst system and a cocatalyst selected from the group consisting of trialkylboron, trialkylsiloxyalutninum, and a combination of trialkylboron and thalkylaluminum compounds. The polymerization process must be carefully controlled to produce a copolymer resin having an exceptionally broad molecular weight distribution, extremely high PENT ESCR values, and a natural branch profile that impacts branching preferably into the high molecular weight portion of the polymer. The resulting copolymer resin is especially useful in high stiffness pipe applications.
