-12- - New Transition metal complex having Quinolin-12H-yl group and catalyst composition containing the same for olefin polymerization and methods for preparing ethylene homopolymers or copolymers of ethylene and -olefins using the same

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transition metal catalyst composition having a high catalytic activity for the production of a transition metal compound and an ethylene homopolymer or a copolymer of ethylene and an a-olefin containing the same, and more particularly to a transition metal catalyst composition having a cyclopentadiene derivative And an aryl group and an alkyl group and has a fused structure at the same time, minimizing steric hindrance, facilitating the injection of comonomer, reducing the vibronic mode at high temperature, (2H) -based ligand and not cross-linking ligands to ethylene homopolymers or copolymers of ethylene and a-olefins. The present invention also relates to a process for producing a copolymer of ethylene homopolymer or ethylene and an? -Olefin using the transition metal catalyst composition and a process for producing an ethylene homopolymer or a copolymer of ethylene and? -Olefin prepared by using the transition metal compound or the transition metal catalyst composition, Olefin / RTI
