Dual site catalyst system comprising a hafnocene component for the production of bimodal polyolefins in a single reactor |
摘要 |
The present invention discloses a metallocene catalyst system for producing polyolefins comprising: A. a hafnocene-based catalyst component suitable for producing the high molecular weight fraction of the polyolefin; B. one or more metallocene or post-metallocene components different from the component A and suitable for producing the low molecular weight fraction of the polyolefin; C. an actvating agent having a low or no coordinating capability.
