Metallocene complex and a process for olefin polymerization

Provided compared with the conventional metallocene catalyst, i.e. the higher the comonomer to ethylene and α- olefin uptake to facilitate olefin monomers include propylene copolymer including metallocene complex, having a higher molecular weight producing rubber component, by homopolymerization of propylene in the manufacture of homopolypropylene having a higher melting point, and such a method in the presence of metallocene complexes for olefin polymerization. Also provided one metallocene complex, for example, by the formula [I] represented by (e.g., in one or each indenyl ring 6 having a substituent group, and optionally substituted with one or two in each of the indenyl ring metallocene complex furyl or thienyl group), the olefin polymerization catalyst containing the metallocene complex, and to a method for polymerizing olefins in the presence of the olefin polymerization catalyst or copolymerization.
