【発明の名称】高分子量のオレフィン重合体を製造するための二核性メタロセン触媒

Document Type and Number:

Japanese Patent JP3054130

Kind Code:

B1

Abstract:

A novel dinuclear metallocene complex is disclosed, which is represented by the following formula (I): 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> 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.
