Abstract:
1. An olefin polymerization process, the process comprising: contacting a catalyst composition with an olefin monomer and an olefin comonomer under polymerization conditions to produce an olefin polymer, wherein the catalyst composition comprises catalyst component I, catalyst component II, catalyst component III, an activator, and an optional co-catalyst, wherein: the olefin polymer has a non-bimodal molecular weight distribution and a ratio of HLMI/MI in a range from about 50 to about 500; catalyst component I comprises an unbridged zirconium or hafnium based metallocene compound and/or an unbridged zirconium and/or hafnium based dinuclear metallocene compound; catalyst component II comprises a bridged zirconium based metallocene compound with a fluorenyl group, and with no aryl groups on the bridging group; and catalyst component III comprises a bridged zirconium or hafnium based metallocene compound with a fluorenyl group, and an aryl group on the bridging group.
