The present invention relates to a method for preparing a polyolefin having a wide molecular weight distribution. More specifically, provided is a method for preparing a polyolefin having a wide molecular weight distribution and an ultra-high molecular weight since a metallocene catalyst containing, as a molecular weight controller (that is, a molecular weight enhancer), an organometallic complex comprising a specific Ti-Al complex structure is used for the polymerization of olefin monomers, thereby enabling both solution polymerization and slurry polymerization and, particularly, enabling the molecular weight distribution to be more readily and effectively controlled. |
