Catalyst composition, method of polymerization, and polymer therefrom

摘要: Catalyst compositions and methods, useful in polymerization processes, utilizing at least two metal compounds are disclosed. At one of the is a Group 15 containing compound other preferably bulky ligand metallocene-type catalyst. The invention also discloses new polyolefin, generally polyethylene, particularly multimodal polymer more specifically, bimodal polymer, its use various end-use applications such as film, molding pipe.
