The invention relates to a metallocene complex (1) according to formula (I) 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 bridging group containing at least one carbon atom bonded to the indenyl moiety at 2-position, R1, R2, R3 and R4 are each independently chosen from the group consisting of H, a halogen atom and a C1-C20 hydrocarbylgroup, and wherein at least one of R1 and R2 is not H, and at least one of R3 and R4 is not H. 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.
该发明涉及一种配合物(1),其化学式为(I),其中M是从元素周期表的3、4、5或6族中选择的镧系元素或过渡金属,Q是与M形成阴离子配体,k是Q基团的数量,等于M的化合价减2,R是含有至少一个碳原子的桥联基团,与2-位置的茚基团键合,R1、R2、R3和R4分别来自H、卤素原子和C1-C20烃基的群,其中至少一个R1和R2不是H,至少一个R3和R4不是H。该发明还涉及包含该配合物的催化剂,制备聚烯烃的方法以及利用聚烯烃制造物品的用途。
