Abstract:
Methods for preparing single and dual metallocene catalyst systems containing an activator-support are disclosed. These methods can include precontacting of the activator-support and an organoaluminum compound, as well as sequential contacting of two different metallocene compounds to form a dual metallocene catalyst system.
