Supramolecular control over the stereochemistry of diene polymers

Abstract

The intermolecular interactions that lead to translational and alternate molecular stacking of 1,3-diene monomers in the solid state (see example, X=CO2CH2-C6H4OCH3) as well as the molecular symmetry of muconic acid derivatives have been utilized in controlling the stereoregularity of polymers. This crystal engineering approach has enabled the four kinds of stereoregular diene polymers to be synthesized in a solid-state polymerization.
