Abstract:
The present invention relates to a supported catalyst comprising a novel metallocene compound having excellent polymerization activity, and a method for producing polypropylene comprising polymerizing propylene in the presence of the catalyst. The supported metallocene-catalyst of the present invention can produce a polypropylene having a relatively narrow molecular weight distribution and a SPAN value.
