Abstract:
Methods for preparing metallocene-based catalyst systems containing an activator-support are disclosed. These methods can include contacting a solid metallocene compound, an activator-support, and an organoaluminum compound, resulting in catalyst systems with increased catalytic activity as compared to catalyst systems utilizing a solution of the metallocene compound.
