Patent ID: 7220804

Claim:
A method for preparing a supported catalyst composition the method comprising the steps of: (a) contacting an activator with a porous support material to form a supported activator, said activator comprising one of an alumoxane, a modified alumoxane, a neutral ionizing activator or an ionic ionizing activator; and (b) contacting the supported activator and a mineral oil with a combination comprising a ligand selected from the group consisting of cyclopentadienyl ligands, indenyl ligands, benzindenyl ligands, fluorenyl ligands, octahydro-fluorenyl ligands, cyclopentacyclododecene ligands, pentalene ligands and hydrogenated versions thereof and a metal compound; wherein the metal compound is represented by the formula: ML x wherein M is a Group 4 metal from the Periodic Table of Elements and L is selected from the group consisting of hydrogen, halogen, hydrocarbyl, alkoxide, aryoxide, carboxylate, carbodionate, amide, carbamate and phosphide; and “x” is an integer depending on the valence state of metal wherein the ligand and the metal compound are contacted with the supported activator as separate components to form the supported catalyst composition.
