ABSTRACT:
A catalyst system comprising a hafnocene catalyst compound and zirconocene catalyst compound, wherein the hafnocene and/or zirconocene include(s) at least one ligand substituted with at least one linear or iso alkyl group having 3 or more carbon atoms is provided. A process for polymerizing olefin(s) using the same catalyst system is also provided.
