Synthesis of 'living' polyolefins with soluble Ziegler-Natta catalysts and application to block copolymerization

“Living” polymerization is of great utility both in understanding the mechanism of chain propagation reactions and in synthesizing well-defined block copolymers. In this review we deal with the development of soluble Ziegler-Natta catalysts for the living coordination polymerization of ethylene and α-olefins and discuss the possibility of synthesis of new block copolymers.
