    摘要: A novel dinuclear metallocene complex is disclosed, which is represented by the following formula (I): wherein M1 and M2 are the same or different and are independently selected from the group consisting of Group IIIB, Group IVB and Group VB transition metals; each X is the same or different and is indepedently an anionic ligand with −1 valence, which is selected from the group consisting H, C1-20 hydrocarbyl, halogen, C1-20 alkoxy, C1-20 aryloxy, NH2, NHR11, NR11R12, —(C═O)NH2, —(C═O)NHR13, and —(C═O)NR13R14, wherein R11, R12, R13 and R14 are C1-20 alkyl; i is an integer from 1 to 3; j is an integer from 1 to 3, R1, R2, R3, R4, R5, R6, R7, and R8 are the same or different and are independently H, a C1-20 linear, branched or cyclic hydrocarbyl group, or a C2-4 cyclic hydrocarbylene group which forms a C4-6 fused ring system; Y1 and Y2 are the same or different and each is an electron-donating group independently selected from a Group 15 or Group 16 element; R9 and R10 are the same or different and each is a divalent radical selected from (—C(R15)2—)p, (—Z(R15)2—)p, or (—Z(R15)2—C(R15)2—)p, Z being silicon, germanium, or tin, R15 being C1-6 alkyl, p being an integer from 1 to 4; R16 is a divalent unsubstituted or alkyl-substituted cyclic alkylene group; and each R17 is independently a C1-20 linear, branched or cyclic hydrocarbyl group. By using the dinuclear metallocene complex as the catalyst, a high molecular weight olefin polymer can be obtained.
