    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.

    Abstract translation: 提供了一种茂金属络合物，其促进烯烃单体（包括丙烯）以更高的共聚单体（即乙烯和α-烯烃）的吸收速率的共聚，制备具有较高分子量的橡胶组分，以及制造具有较高熔点的均聚丙烯 与传统的茂金属催化剂相比，丙烯的均聚，以及在这种茂金属络合物存在下烯烃聚合的方法。 还提供了例如由通式[I]表示的茂金属络合物（例如，在一个或每个茚基环的6位上具有取代基的金属茂络合物和位置2上任选取代的呋喃基或噻吩基的一个或多个 茚基环），含有茂金属络合物的烯烃聚合催化剂，以及在烯烃聚合催化剂存在下进行烯烃聚合或共聚的烯烃聚合方法。
