Abstract:
1. A polymerization process, the process comprising: (1) contacting a dual catalyst system with an olefin monomer and an olefin comonomer in a polymerization reactor system under polymerization conditions to produce an olefin polymer, wherein the olefin polymer comprises a higher molecular weight component and a lower molecular weight component, wherein the dual catalyst system comprises a first metallocene catalyst component and a second metallocene catalyst component, and wherein the polymerization conditions comprise a reaction temperature and a dual catalyst system residence time; and (2) controlling a weight ratio of the higher molecular weight component to the lower molecular weight component by adjusting the reaction temperature and/or the dual catalyst system residence time, wherein the weight ratio of the higher molecular weight component to the lower molecular weight component increases as the reaction temperature increases.
