Selected successful examples for precise synthesis of new polyolefins by coordination insertion polymerization, especially by copolymerization of ethylene with new comonomer (s) using newly designed complex catalysts have been introduced. Efficient copolymerization of ethylene with styrene can be achieved by so called half-titanocene catalysts, and the ligand modification should play an essential key role especially for the efficient styrene incorporation. Efficient introduction of functional group into polyolefins has also been achieved by the (direct) copolymerization using <i>nonbridged</i> half-titanocenes, and a new synthetic strategy for precise, efficient synthesis of polyolefins containing polar functionalities with uniform compositions (as well as with uniform molecular weight distribution) under mild (environmentally benign) conditions can be demonstrated.
