ABSTRACT:
The present invention relates to catalyst supports and improvements thereof for use with supported activators and supported transition metal catalyst systems. The invention specifically involves reacting a carrier containing reactive functionalities, e.g., hydroxyl containing silica, with halogenated organic compounds, e.g., fluorosubstituted phenols. The reaction is preferably carried out in the presence of a base. The reaction consumes undesired functionalities on the support to provide a halogenated support which is suitable for activators and catalytic precursors which are adversely affected by functionalities typically found on supports. The supported activators or catalytic precursors are prepared by contacting the precursors or activators with the halogenated support.
