Abstract
The present invention relates to a method for preparing polyolefin that can easily and effectively prepare polyolefin having high molecular weight and various molecular weight distributions, which was difficult to prepare using the existing metallocene catalyst, and polyolefin prepared thereby. The method for preparing polyolefin comprises the step of polymerizing olefin monomers, in the presence of a metallocene supported catalyst wherein a metallocene compound having a specific chemical structure is supported in a carrier, and hydrogen gas.
