ABSTRACT:
The present invention relates to a multinuclear metallocene catalyst for olefin polymerization and a process for olefin polymerization using the same, in which the multinuclear metallocene catalyst for olefin polymerization comprises, as a main catalyst, a transition metal compound that contains at least two metal atoms in the groups III to X of the periodic table as central metals and a ligand having a cyclopentadienyl structure bridging between the two metal atoms, and, as a cocatalyst, an aluminoxane compound, an organoaluminum compound or a bulky compound reactive to the transition metal compound to impart a catalytic activity to the transition metal compound.
