Ring-Opening Metathesis Polymerization of Alkyl Substituted trans-Cyclooctenes

Abstract

The synthesis and ring-opening metathesis polymerization of highly-strained 3- and 1-butyl substituted trans-cyclooctenes (monomers 1 and 2, respectively) was investigated with the goal of quickly preparing regioregular polymers with narrow molecular weight distributions, which could serve as precursors for high precision short-chain branched polyethylene. Monomer 1 was unable to be polymerized in a regioregular manner, however monomer 2 did yield regioregular product, although the polydispersity indices were higher than expected. Investigation by NMR provided evidence that the nature of the propagating alkylidene is likely non-uniform throughout the course of the reaction, leading to the broadened molecular weight distribution.
