Title:
CATALYST COMPOSITION, METHOD FOR PREPARING SAME, AND METHOD FOR PREPARING POLYOLEFINS USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/208851
Kind Code:
A1
Abstract:
The present invention relates to a catalyst composition capable of preparing polyolefins having a high molecular weight, a method for preparing same, and a method for preparing the polyolefins using same. The binucleate metallocene compound comprised in the catalyst composition according to the present invention has a novel structure and can provide a multi-site catalyst exhibiting high activity by having high substrate accessibility unlike a single-site catalyst.
