Transition metal compound, catalyst for olefin polymerization containing the same, and method for producing propylene/ethylene-α-olefin block copolymer by using the catalyst |
摘要 |
Disclosed is a novel transition metal compound which is used for forming a metallocene catalyst for olefin polymerization. Specifically disclosed is a novel transition metal compound represented by the general formula below which enables to form a metallocene catalyst that has a balanced reactivity with ethylene and a comonomer selected fromα-olefins having 3-20 carbon atoms and enables to produce anα-olefin polymer having a high molecular weight. Also specifically disclosed are a catalyst for olefin polymerization containing such a transition metal compound, and a method for producing a propylene/ethylene-α-olefin block copolymer wherein such a catalyst is used.
