摘要
Olefin polymerization catalyst systems including a high molecular weight catalyst compound and a low molecular weight catalyst compound, and methods of making same are provided. High molecular weight catalysts include metallocene catalysts and low molecular weight catalysts include non-metallocene compounds including biphenyl phenol compounds. Generally catalyst systems may include less than about 5.0 mol % of the high molecular weight catalyst compound relative to said low molecular weight catalyst. Methods for olefin polymerization including the aforementioned catalyst systems, and polyolefins and products made therefrom.
