Document Type and Number:
WIPO Patent Application WO/2019/038605
Kind Code:
A1
Abstract:
Provided are a novel transition metal compound based on a cyclopenta[a]naphthalene group, a transition metal catalyst composition having high catalytic activity for preparing an ethylene homopolymer or a copolymer of ethylene and at least one α-olefin including the same, a method for preparing an ethylene homopolymer or a copolymer of ethylene and α-olefin using the same, and the ethylene homopolymer or the copolymer of ethylene and α-olefin prepared above. The metallocene compound according to the present invention and the catalyst composition including the same may provide a high thermal stability of the catalyst to maintain high catalytic activity even at a high temperature, have good copolymerization reactivity with other olefins, and prepare a high molecular weight polymer at a high yield.
