GROUP 4 METAL COMPOUND OF THIOPHENE-FUSED CYCLOPENTADIENYL LIGAND TETRAHYDROQUINOLINE DERIVATIVE, AND OLEFIN POLYMERIZATION USING SAME

摘要

The present invention relates to a novel ligand and a transition metal complex prepared using same, the novel ligand being derived from a tetrahydroquinoline derivative, and having a condensed ring formed by an amido ligand and ortho-phenylene, and a five-membered ring pi-ligand that is combined to the ortho-phenylene and fused using a thiophene hetero ring. When activated by a cocatalyst in olefin polymerization, the novel transition metal complex provides the advantage of having higher activity compared to a catalyst that is not fused by a thiophene hetero ring, and of providing a polymer having a higher molecular weight.
