The invention relates to a novel process for producing a supported metallocene catalyst system useful for the polymerization and/or copolymerization of olefins, alpha-olefins, and/or diolefins which results in a catalyst product which during polymerization, produces minimal to no reactor fouling and polymer of controlled morphology. The invention is particularly useful for but not limited to polymerizing propylene or copolymerizing propylene with olefins having two or more carbon atoms. The novel support technique described herein results in a catalyst which will obtain polymer product having controlled, uniform particle size, narrow molecular weight distribution, high bulk density and depending upon the metallocene employed and monomers polymerized, stereoregularity.
A method to produce a supported metallocene/alumoxane catalyst system comprising the steps of:
