NOVEL TRANSITION METAL COMPOUND, CATALYST FOR OLEFIN POLYMERIZATION CONTAINING THE SAME, AND METHOD FOR PRODUCING PROPYLENE/ETHYLENE-a-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 from a-olefins having 3-20 carbon atoms and enables to produce an a-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-a-olefin block copolymer wherein such a catalyst is used.
