Abstract:
This invention relates to metallocene catalyst systems and to methods for their production and use. Specifically, this invention relates to catalyst promoters which increase the activity of the metallocene catalyst systems. The promoters can be, for example, styrene or substituted styrene in one embodiment. The metallocene catalyst systems can be used, for example, to make olefins. The catalyst systems of this invention can be supported.
