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.

Abstract: Provided are a catalyst composition and a method of oligomerizing olefins using the same. When the catalyst composition according to the present invention is used, oligomerization and copolymerization of olefin monomers may be performed in a single reactor at the same time with high efficiency without a separate process of preparing alpha-olefin. Therefore, costs for preparing or purchasing comonomers which are expensive raw materials may be reduced, thereby reducing the production cost of a final product. Contents of SCB (short chain branch) and LCB (long chain branch) in the polyolefin may be increased without separate feeding of comonomers, thereby producing high-quality linear low-density polyethylene.
