    摘要: A process for the preparation of a catalyst system includes the steps of combining a Lewis base, an organic compound having at least one functional group containing active hydrogen, and an organometallic component with a particulate support material to provide an intermediate composition, and then combining the intermediate composition with one or more metallocene compound. The catalyst system is advantageously used for olefin polymerization.

    摘要: A process for the preparation of a catalyst system includes the steps of combining a support material with a first composition which includes at least one aluminoxane in a first solvent to provide an aluminoxane loaded support; and, contacting the aluminoxane loaded support with a second composition which includes at least one metallocene compound, a second solvent, and a cocatalyst, wherein the cocatalyst includes a second portion of the at least one aluminoxane alone or in combination with an ionic compound and/or a Lewis acid.
