Catalyst systems, polymers and methods of forming the same are described herein. The catalyst systems generally include an inorganic support material having a bonding sequence selected from Si-O-Al-F, F-Si-O-Al, F-Si-O-Al-F and combinations thereof, wherein the inorganic support material has an acid strength (pKa) of less than about 4.8 and a transition metal compound, wherein the transition metal compound is represented by the formula [L]<SUB>m</SUB>M[A]<SUB>n</SUB>; wherein L is a bulky ligand, A is a leaving group, M is a transition metal and m and n are such that a total ligand valency corresponds to a transition metal valency. |
