Patent ID: 7060766

Claim:
A method of polymerizing olefins comprising combining: (a) ethylene and optionally one or more C 3 to C 10 α-oleflns; and (b) a catalyst composition formed by combining: (i) a halogenated aromatic aluminum activator compound, wherein the halogenated aromatic aluminum activator compound has the formula R n Al(ArHal) 3-n , wherein ArHal is a halogenated aryl group, R is a monoanionic ligand, and n is 1 or 2, and (ii) a fluorinated support and one or more catalysts to form a supported activated catalyst composition; wherein the fluorinated support possesses from 0.001 mmol OH/g support to 1 mmol OH/g support; (iii) isolating a supported activator composition; then (iv) combining the supported activator composition with a catalyst compound.
