Abstract
The present invention provides a method for preparing a polyolefin having a broad molecular weight distribution. More specifically, the present invention provides a method for preparing a polyolefin having a broad molecular weight distribution and an ultra-high molecular weight in which an organometallic complex containing a specific Ti—Al complex structure is used as a molecular weight controller (i.e., molecular weight enhance) in the polymerization of an olefin monomer, thereby enabling both solution polymerization and slurry polymerization, particularly enabling the molecular weight distribution to be more readily and effectively controlled.
