Abstract
This invention relates to supported metallocene catalyst systems and to methods for their production and use. Specifically, this invention relates to supported catalyst systems having unique, predetermined properties resulting from the designed distribution of catalyst components within and upon porous support particles. The designed distribution of catalyst components is obtained through sequential deposition of catalyst components with intervening removal of solvent.
