ABSTRACT:
A solid metallocene-containing catalyst system of an organoaluminoxane, at least one metallocene having at least one olefinically unsaturated substituent and a polyolefin is disclosed. The polyolefin is formed from at least one olefin polymerized in the presence of a combination of a solution of the organoluminoxane in an aromatic liquid, the at least one metallocene, and an aliphatic liquid. The solid metallocene-containing catalyst system may also include one or more the particulate solids.
