METHOD FOR PREPARING POLYOLFIN AND POLYOLEFIN PREPARED THEREFROM

摘要

The present invention relates to a production method of polyolefin enabling users to effectively produce the polyolefin which can be preferably used for blow molding by having large molecular weight and multimodal molecular weight distribution and the polyolefin produced by the method. The production method of the polyolefin includes a step of polymerizing an olefin based monomer under the presence of a metallocene catalyst and a small amount of molecular weight adjusting agent.
