<p>Methods of forming supported catalyst systems, supported catalyst systems and polymerization processes utilizing supported catalyst systems are described. The methods include providing an inorganic support material, contacting the inorganic support material with a support solvent to form a support solution, and contacting the support solution with a fluorine containing compound (AlFpX3−pBq) to form an intermediate. X is Cl, Br or OFF, B is H2O, p is from 1 to 3 and q is 0 to 6. The methods include drying and heating the intermediate to at least about 300° C. to form an impregnated support and contacting the impregnated support with a transition metal compound ([L]mM[A]n) to form a supported catalyst system. 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 the transition metal valency.</p> |
