SUPPORTED METALLOCENE CATALYST, METHOD FOR PREPARING THE SAME AND METHOD FOR PREPARING POLYOLEFIN USING THE SAME |
摘要 |
Provided are a supported metallocene catalyst, a method for preparing the same and a method for preparing polyolefin using the same. The supported metallocene catalyst prepared by incorporating a metallocene compound having a ligand substituted with alkoxide or aryloxide into a conventional supported metallocene catalyst and incorporating a borate compound as a second co-catalyst exhibits considerably superior catalyst activity and easily controls molecular weight distribution, as compared to the conventional metallocene-supported catalyst. |
