Transition metal compound, olefin polymerization catalyst component comprising the transition metal compound, olefin polymerization catalyst comprising the olefin polymerization catalyst component, and process for olefin polymerization |
摘要 |
Disclosed is a novel transition metal compound represented by the following formula: <IMAGE> wherein M is a transition metal, X is halogen or the like, R1 is a hydrocarbon group or the like, R2 is an aryl group substituted with a halogenated hydrocarbon group, and Y is a divalent silicon-containing group or the like. Also disclosed are an olefin polymerization catalyst component comprising the transition metal compound, an olefin polymerization catalyst comprising the olefin polymerization catalyst component, and a process for olefin polymerization using the olefin polymerization catalyst. An olefin polymerization catalyst component having high polymerization activity can be formed from the transition metal compound. By the use of the olefin polymerization catalyst or the process for olefin polymerization, polyolefins having a high melting point and a high molecular weight can be prepared with high polymerization activity.
