PROCESS FOR THE PREPARATION OF AN UNSUPPORTED OLEFIN POLYMERISATION CATALYST AND POLYMERISATION CATALYST PREPARED THEREBY

摘要

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.
