CATALYST FOR POLYOLEFIN PRODUCTION AND PROCESS FOR PRODUCING POLYOLEFIN

摘要

A catalyst component for polyolefing production, comprising a metallocene compound of general formula (1) (the characters used in the formula having the meaning as set forth in the text of Description); a catalyst for polyolefin production comprising the component; and a process for producing polyolefins wherein the catalyst is used. The polymerization of an alpha -olefin, especially, propylene in the presence of the catalyst comprising the novel metallocene compound of the invention as a component thereof enables production of an isotactic polyolefin having its stereoregularity and positional regularity highly controlled, especially, an isotactic polypropylene of high positional regularity whose production has been difficult with the use of the conventional metallocen catalysts.
