Document Type and Number:
WIPO Patent Application WO/2011/040753
Kind Code:
A2
Abstract:
According to the present invention, a novel supported hybrid metallocene catalyst comprises a catalyst precursor and a supporting material for supporting the catalyst precursor, wherein said catalyst precursor comprises a phenoxyimine-based metal compound and two metallocene compounds which are different from each other. When polyolefins are polymerized using the supported hybrid metallocene catalyst of the present invention, molecular mass distribution can be controlled, and the activity of the catalyst can be improved.
