  • GAS PHASE POLYMERISATION OF ETHYLENE
    Publication number: 20150099855
    Abstract: The present invention is directed to a process for the gas phase polymerisation of ethylene in the presence of a catalyst composition comprising a support material carrying a chromium compound and a magnesium containing compound represented by the formula R1MgX, wherein R1 is a (C1-C20) hydrocarbon group and X is a halogen atom wherein the molar ratio chromium to magnesium ranges between 10:1 and 1:1.
    Type: Application

  • Alumoxane-enhanced, supported ziegler-natta polymerization catalysts, methods of making same, processes of using same and polymers produced therefrom
    Patent number: 6124412
    Abstract: The present invention relates to a new olefin polymerization catalyst composition, and methods of preparing and methods of using the catalysts to polymerize various olefinic monomers in either gas or slurry phase reactions. The principal advance over the previous art of record involves using alumoxanes or combinations of alumoxanes as catalyst preactivators. Polymers prepared from these catalysts posses productivity increased as high as 40 percent. At the same time, the bulk density remains relatively constant. Additionally, the total amount of cocatalyst species needed to effectively practice the invention is relatively low.
