METHOD FOR PREPARING SUPPORTED HYBRID METALLOCENE CATALYST, AND SUPPORTED HYBRID METALLOCENE CATALYST USING THE SAME

摘要

Provided is a method for producing a hybrid-supported metallocene catalyst which can be used for producing polyolefin. Also, provided are a hybrid-supported metallocene catalyst produced by using the same and a method for producing polyolefin using the hybrid-supported metallocene catalyst. According to the present invention, it is possible to produce the hybrid-supported metallocene catalyst used for polymerizing olefin-based polymers which have the ultrahigh molecular weight and exhibit high polymerizing activities. To this end, the method includes the following steps: supporting a first co-catalyst onto a carrier; supporting a first metallocene compound onto the carrier on which the first co-catalyst is supported; supporting a second co-catalyst onto the carrier on which the first co-catalyst and the first metallocene compound are supported; and supporting a second metallocene compound which polymerizes an olefin-based monomer at the less polymerization rate than the first metallocene compound, onto the carrier on which the first co-catalyst, the first metallocene compound, and a second co-catalyst are supported.
