ABSTRACT:
Supported olefin polymerization catalyst systems can be produced using waste chromium compounds. Olefin polymers can be prepared using a catalyst system composition comprising a waste chromium compound and an alkyl aluminum compound, both supported on an inorganic oxide support, wherein at least a portion of the waste chromium compound is in a hexavalent state.
