Organometallic catalysts for copolymerization of cyclic olefins

This article provides an overview on recent progress in the addition copolymerization of ethylene or α-olefins with cyclic olefins by various organometallic catalysts. Special emphasis is placed on the catalyst structures that govern the copolymerization activity, comonomer incorporation, and the tacticity, molecular weight and thermal property of the resulting copolymers.
