Equimolecular binary polydines. V. Equibinary poly(<i>cis</i>‐1,4–trans‐1,4)butadiene from bis(π‐allyl nickel trifluoroacetate)

Abstract

Abstract The preparation of equibinary poly( cis ‐1,4–trans‐1,4)butadiene was investigated in the presence of bis(π‐allyl nickel trifluoroacetate) modified with suitable additional ligands. The behavior of the catalytic species in the polymerization reaction as well as the specific basic properties of the equibinary polybutadiene produced support obviously a regular distribution of the cis and trans isomers in the polymer chains.
