ABSTRACT:
Polymeric supports, which have been treated with a halosulfonic acid, increase the activity of single-site catalysts used with aluminoxane co-catalysts, resulting in improved ethylene polymerization. The present invention seeks to provide polymeric catalyst supports which have been treated with halosulfonic acid for improved activity.
