Alternating Copolymerization of Ethylene and Butadiene with a Neodymocene Catalyst

Abstract

A new route to poly(ethylene-alt-butadiene) uses a homogeneous neodymocene/dialkylmagnesium catalyst which exhibits high activity and allows the polymerization to be easily controlled, both in terms of molecular weight and microstructure of the product. The s-trans-η4-butadiene complex shown in the picture is thought to be an essential intermediate of this reaction.
