Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a catalyst system for olefin polymerization. SOLUTION: A catalyst system supported with silica for olefin polymerization includes: (a) an activator selected from a group including alumoxanes, ionic borates, ionic aluminates, alkylaluminums, and aluminoborates; and (b) a bridged indenoindolyl group 4 transition metal complex having an architecture of chemical formula wherein bridging to an indenoindolyl group is achieved via an indolyl nitrogen.
