TRANSITION METAL COMPOUND, OLEFIN POLYMERIZATION CATALYST, AND PROCESS FOR PRODUCING OLEFIN POLYMER BY USING SAID CATALYST |
摘要 |
There are herein disclosed a novel transition metal compound useful as a catalytic component for olefin polymerization, a compound usable as a ligand of this transition metal compound, its precursor, a process for efficiently preparing the transition metal compound, and a catalyst for polymerization which contains the transition metal compound and which has a high activity and an excellent copolymerizability and which is capable of forming an olefin polymer having a uniform composition and a narrow molecular weight distribution. The transition metal compound of the present invention is a multiple crosslinking type transition metal complex represented by the general formula (I) <CHEM> wherein M is a metallic element in the groups 3 to 10 or a lanthanoide series of the periodic table; E<1> and E<2> are each a sigma -bonding or a pi -bonding ligand; X is a sigma -bonding ligand; Y is a Lewis base; A<1>, A<2>, ... A<n> and D are each a crosslinking group; n is 2 to 4; p is 1 to 4; q is 1 to 5 Ä(the valence of M)-2Ü; r is 0 to 3; and s is 0 to 4. |
