  • Process to prepare a paticulated metallocene catalyste with a modified aluminoxane and use in polymerization of olefins
    Publication number: 20050239637
    Abstract: A process for the preparation of an olefin polymerisation catalyst comprising: a) reacting an aluminoxane and a Lewis base in an optionally halogenated hydrocarbon solvent to form a particulate suspension; b) reacting said suspension with a metallocene complex in an optionally halogenated hydrocarbon solvent; and optionally c) isolating the olefin polymerisation catalyst.
