Claims
- 1. A supported catalyst system comprising: a Group 15 containing metal catalyst compound, a bulky ligand metallocene-type catalyst compound, a Lewis acid aluminum containing activator and a carrier,
wherein the Lewis acid aluminum containing activator is represented by the following formula: RnAl(ArHal)3-n, wherein R is a monoanionic ligand; ArHal is a halogenated C6 aromatic or higher carbon number polycyclic aromatic hydrocarbon or aromatic ring assembly in which two or more rings are joined directly to one another or together; and n=1 or 2.
- 2. The supported catalyst system of claim 1 wherein the Group 15 containing metal catalyst compound is a Group 15 containing bidentate or tridentate ligated metal catalyst compound.
- 3. The supported catalyst system of claim 1 wherein the Group 15 containing metal catalyst compound and the bulky ligand metallocene-type catalyst compound are contacted with the Lewis acid aluminum containing activator to form a reaction product that is then contacted with the carrier.
- 4. The supported catalyst system of claim 1 wherein the carrier and the Lewis acid aluminum containing activator are combined to form a support bound, neutral Lewis acid aluminum containing activator having at least one ligand covalently bound to a support material.
- 5. The supported catalyst system of claim 4 wherein the support material is a polymeric support or a metal/metalloid oxide support.
- 7. The supported catalyst system of claim 4 wherein the at least one ligand is a heteroatom that is covalently bound to the support material.
- 8. The supported catalyst system of claim 4 wherein the Lewis acid aluminum containing activator further comprises at least two halogenated aryl ligands.
- 9. The supported catalyst system of claim 1 wherein the supported catalyst system further comprises alumoxane.
- 10. A method of making a supported catalyst system, method comprising the steps of:
(a) combining a Group 15 metal containing catalyst compound and a bulky ligand metallocene-type catalyst compound; (b) combining a support material with a Lewis acid aluminum containing activator represented by the formula: RnAl(ArHal)3-n, wherein R is a monoanionic ligand; ArHal is a halogenated C6 aromatic or higher carbon number polycyclic aromatic hydrocarbon or aromatic ring assembly in which two or more rings are joined directly to one another or together; and n=1 or 2; and (c) combining (a) and (b).
- 11. The method of claim 10 wherein in step (b) the Lewis acid aluminum containing activator is covalently bound to the support material.
