Initiator control of the tacticity of ROMP polymers

Abstract

A variety of metal based ROMP initiators have been developed over the past several years that allow precise control of polymer structure. Recently initiators based on molybdenum and ruthenium that provide control of the double bond geometry of the resulting polymers. Many of these also provide precise control of the tacticity of the backbone. Metallocene catalysts provide good models for thiis control.
