  • Fluidized bed gas phase process of preparing a supported metallocene catalyst
    Patent number: 5789332
    Abstract: The present invention is directed to a gas phase process of preparing a supported metallocene catalyst wherein an alkylaluminum compound, water, a metallocene and, optionally, an olefin are metered into a fluidized bed reactor containing a fluidized bed of an inert support material in the presence of a gas stream.

  • Process for preparing aluminoxane on inert support material
    Patent number: 5534474
    Abstract: The invention relates to a process for preparing alkylaluminoxanes immobilized on inert support materials from alkylaluminum compounds and water, which is characterized in that the reactants are metered with the gas stream into a fluidized-bed reactor and the reaction product is fixed on the support directly from the gas phase.
