Abstract

The present invention relates to a supported catalyst for olefin polymerization to which a novel transition metal compound and a co-catalyst compound are bound, and a preparation method for polyolefin using the supported catalyst. The transition metal compound bound to the catalyst of the present invention provides high activity for olefin-based monomers in heterogeneous reaction as well as in homogeneous system. Particularly, a polyolefin with higher molecular weight can be prepared by using the supported catalyst containing the transition metal compound bound to a support, rather than using the novel transition metal compound in a non-supported status, or the conventional transition metal compound in a supported or non-supported status.
