Abstract:
1. An olefin polymerization process, the process comprising: contacting a catalyst composition with an olefin monomer and optionally an olefin comonomer under polymerization conditions to produce an olefin polymer, wherein the catalyst composition comprises catalyst component I, catalyst component II, an activator-support comprising a solid oxide treated with an electron-withdrawing anion, and an organoaluminum compound, wherein a molar ratio of catalyst component I to catalyst component II in the catalyst composition is in a range from about 6:1 to about 75:1; wherein a melt index (MI) of the olefin polymer produced by the process is at least 10% less than a MI of an olefin polymer obtained under the same polymerization conditions without catalyst component II; wherein catalyst component I comprises: formula (C) is wherein: M X E R Cp formula (D) is wherein: M X E R wherein catalyst component II comprises:  a compound having the formula  or any combination thereof, wherein: M X Cp E
