Abstract
A dinuclear transition metal compound of Formula 1 is provided: where R, R, R, R, R, R, L, A, B, X, M, z, and n are the same as in the description of the present invention. The dinuclear transition metal compound includes two transition metal compounds connected each other by a bridging group so that a decrease in catalyst activation due to a polar functional group can be prevented. A catalyst composition including the dinuclear transition metal compound is highly active for a monomer having a polar functional group.
