Abstract
Provided are a metallocene complex that facilitates copolymerization of olefin monomers including propylene at a higher uptake rate of comonomers, i.e., ethylene and α-olefin, manufacture of a rubber component having a higher molecular weight, and manufacture of homopolypropylene having a higher melting point through homopolymerization of propylene, compared to traditional metallocene catalysts, and a method of olefin polymerization in the presence of such a metallocene complex. Also provided are, for example, a metallocene complex represented by general formula [I] (e.g., a metallocene complex having a substituent at position 6 of one or each indenyl ring and an optionally substituted furyl or thienyl group at position 2 of one or each indenyl ring), an olefin polymerization catalyst containing the metallocene complex, and a method of olefin polymerization involving olefin polymerization or copolymerization in the presence of the olefin polymerization catalyst.
