NEW TRANSITION METAL COMPLEX WITH ANNULATED RING SUBSTITUTED ARYLPHENOXY LIGAND, CATALYST COMPOSITION CONTAINING THE SAME FOR OLEFIN COPOLYMERIZATION AND METHODS FOR PREPARING COPOLYMERS OF ETHYLENE AND -OLEFINS OR COPOLYMERS OF ETHYLENE AND OLEFIN-DIENE USING THE SAME

摘要

PURPOSE: A transition metal compound or a catalyst composition containing the compound is provided to enable easy and cheap preparation of the compound or the composition and to have copolymer reactivity with other olefins with a high catalytic activity at high temperature. CONSTITUTION: A transition metal compound is denoted by chemical formula 1. A transition metal catalyst composition for preparing a copolymer of ethylene and alpha-olefin or ethylene and olefin-diene contains: the transition metal compound; and an aluminum compound cocatalyst, a boron compound cocatalyst, or a mixture thereof. The cocatalyst is prepared using a transition metal catalyst composition.
