<p>A novel dinuclear metallocene complex is disclosed, which is represented by the following formula (I): <CHEM> wherein M<1> and M<2> 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, NHR<11>, NR<11>R<12>, -(C=O)NH2, - (C=O)NHR<13>, and -(C=O)NR<13>R<14>, wherein R<11>, R<12>, R<13> and R<14> are C1-20 alkyl; i is an integer from 1 to 3; j is an integer from 1 to 3, R<1>, R<2>, R<3>, R<4> , R<5>, R<6>', R<7> and R<8> 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; Y<1> and Y<2> <are> the same or different and each is an electron-donating group independently selected from a Group 15 or Group 16 element; R<9> and R<10> are the same or different and each is a divalent radical selected from (-C(R<15>)2-)p, (-Z(R<15>)2-)p, or (-Z(R<15>)2-C(R<15>)2-)p, Z being silicon, germanium, or tin, R<15> being C1-6 alkyl, p being an integer from 1 to 4; R<16> is a divalent unsubstituted or alkyl-substituted cyclic alkylene group; and each R<17> 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. <IMAGE></p> |
