Abstract:
A composition useful for activating catalysts for olefin polymerization is provided. The composition is derived from at least: carrier; organoaluminoxy compound; component having at least one electron withdrawing group and at least one active proton; and Lewis base. Alternatively, the composition is derived from at least: carrier; organoaluminoxy compound; component having at least one electron withdrawing group and at least one active proton; and ionic compound having at least one active proton. Alternatively, the composition is derived from at least: carrier; organoaluminoxy compound; component having at least one electron donating group and at least one active proton; and, optionally, Lewis base. Alternatively, the composition is derived from at least: carrier; organoaluminoxy compound; component having at least one electron withdrawing group and at least one active proton; and component having at least one electron donating group and at least one active proton—and optionally, the composition comprises Lewis base.
