Abstract: The present invention relates to a process for preparing a catalyst for olefin polymerization. Specifically, the present invention relates to a process for preparing a supported metallocene catalyst capable of producing a polyolefin in which the formation of gels is suppressed. In the process for preparing a supported metallocene catalyst according to an embodiment of the present invention, it is treated with a metallic stearate after a transition metal compound has been supported, which suppresses the formation of a macromolecular polyolefin. Thus, a polyolefin with minimal gel formation can be prepared.

Abstract: The present invention relates to an olefin-based polymer, and a method for preparing the same. The olefin-based polymer according to an embodiment of the present invention has a wide molecular weight distribution and thus has excellent processability. Moreover, a relatively large number of short-chain branches are present in high molecular weight components of the olefin-based polymer, and thus the olefin-based polymer has excellent mechanical strength and heat-sealing properties.
