Patent ID: 7452948

Claim:
A method for the preparation of a supported polymerisation catalyst system, said method comprising combining (i) a porous support, (ii) a polymerisable monomer, (iii) a metallocene complex having the formula: CnMXn wherein Cp is a single cyclopentadienyl or substituted cyclopentadienyl group optionally covalently bonded to M through a substituent, M is a Group IVB metal bound in a η 5 bonding mode to the cyclopentadienyl or substituted cyclopentadienyl group, X each occurrence is hydride or a moiety selected from the group consisting of halo, alkyl, aryl, aryloxy, alkoxy, alkoxyalkyl. amidoalkyl, and siloxyalkyl having up to 20 non-hydrogen atoms and neutral Lewis base ligands having up to 20 non-hydrogen atoms or optionally one X together with Cp forms a metallocycle with M and n is dependent upon the valency of the metal, and (iv) a cocatalyst, wherein (i) to (iv) are combined in the order of (a)addition of the cocatalyst to the porous support, (b)addition of the polymerisable monomer, and (c)addition of the metallocene complex.
