CATALYST FOR POLYOLEFIN PRODUCTION AND PROCESS FOR PRODUCING POLYOLEFIN

摘要

A catalyst component for polyolefin production catalysts comprising a metallocene compound represented by general formula (1) (symbols have the meanings as described in the specification), polyolefin production catalyst containing the component, and method for producing polyolefin with the catalyst are provided. Use of a catalyst containing the novel metallocene compound as a catalyst component of the invention in polymerization of alpha -olefin, particularly propylene, enables one to prepare high rigid, high melting point isotactic polypropylene useful as an industrial material for automobiles and the like, more specifically isotactic polypropylene having highly controlled stereoregulartity and regioregularity, particularly the one having a high regioregularity that has been difficult to achieve with conventional metallocene catalysts.
