ABSTRACT:
Metallocene-containing catalyst compositions that include inert filler, a method for their preparation, and a method for their use in production of polyolefins are disclosed and claimed. The catalyst compositions contain solid particles of a mixture comprising a) a metallocene catalyst; b) a cocatalyst capable of activating said metallocene catalyst; and c) particulate filler material having an average particle size of less than about 10 micrometers that is unreactive with the metallocene catalyst and the cocatalyst. They are prepared by spray drying a slurry of the constituents.
