SUPPORTED CATALYST FOR POLYMERIZING OLEFIN AND METHOD FOR PREPARING POLYOLEFIN USING SAME

WIPO Patent Application WO/2011/129592

A2

The present invention relates to a supported catalyst for polymerizing olefin that is supported by a transition metal compound having a novel structure and a cocatalyst compound, and to a method for preparing a polyolefin using same. The transition metal compound supporting the catalyst of the present invention, shows high activity for olefin-based monomers, not only in homogeneous reactions but also in heterogeneous reactions. More particularly, when the supported catalyst that is supported by the transition metal compound is used, polyolefins with higher molecular weight can be prepared compared to when the transition metal compound is used in a non-supported state or when conventional transition metal compounds are used in a supported or non-supported state.
