PROCESS TO PREPARE A PARTICULATED METALLOCENE CATALYST WITH A MODIFIED ALUMINOXANE AND USE IN POLYMERIZATION OF OLEFINS

摘要

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.
