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, and an activator, wherein the activator comprises an aluminoxane compound, an organoboron or organoborate compound, an ionizing ionic compound, or any combination thereof; 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 an amount of the olefin polymer produced per hour by the process is at least 10% greater than an amount of an olefin polymer obtained per hour under the same polymerization conditions without catalyst component II; 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
