Abstract
This invention is generally directed toward a supposed catalyst system useful for polymerizing olefins. The method for supposing the catalyst of the invention provides for a supposed metallocene catalyst able to produce polymers having broader molecular weight distribution and a higher molecular weight. Not only are such polymers easily processable as compared with metallocene polymers produced with other support methods but the methods of this invention provides for a supposed catalyst with increased activity.
