The invention relates to a metallocene complex according to formula I or II wherein M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements, Q is an anionic ligand to M, k is the number of Q groups and equals the valence of M minus 2, R is a divalent bridging group, R1, R2, R3 and R4 are each independently chosen from the group consisting of hydrogen (H); a halogen atom; a silyl, alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl group; and R5, R6, R7 and R8 are each independently chosen from the group consisting of hydrogen (H); a halogen atom; a silyl, alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl group; or two adjacent radicals R5 and R6, R6 and R7, and R7 and R8 are connected with each other in a hydrocarbon ring system. The invention also relates to a catalyst comprising the metallocene complex, to a process for making polyolefins and to the use of the polyolefins for making articles.
该发明涉及一种配位基于公式I或II的金属环戊二烯络合物,其中M是来自元素周期表3、4、5或6族的镧系元素或过渡金属的金属,Q是连接到M的阴离子配体,k是Q基团的数量,等于M的价数减去2,R是二价桥联基团,R1、R2、R3和R4分别独立地选择自氢(H)、卤素原子、硅烷基、烷基、环烷基、芳基、烷基芳基或芳基烷基群;R5、R6、R7和R8分别独立地选择自氢(H)、卤素原子、硅烷基、烷基、环烷基、芳基、烷基芳基或芳基烷基群;或者相邻的基团R5和R6、R6和R7、以及R7和R8在碳氢环系统中相互连接。该发明还涉及包含该金属环戊二烯络合物的催化剂,用于制备聚烯烃的方法以及将聚烯烃用于制造物品的用途。
