Four kinds of stereoregular poly(muconic acid)s, which are synthesized by topochemical polymerization and subsequent solid-state hydrolysis, are used as the organic host materials for intercalation. We describe the reaction behavior and layered structure

We have successfully controlled the stereochemical structure of diene polymers during radical polymerization in the solid state under UV and γ-ray radiation. The polymerization of the substituted benzyl muconates occurred via a crystal lattice controlled reaction mechanism. The polymerization is controlled by not only diisotactic and disyndiotactic, but also meso and racemo structures to afford various kinds of stereoregular polymers. Georg Thieme Verlag Stuttgart.
Supramolecular control over the stereochemistry of diene polymers
Nagahama, Sadamu,Tanaka, Toshihiro,Matsumoto, Akikazu
, p. 3811 - 3814 (2007/10/03)
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.
First disyndiotactic polymer from a 1,4-disubstituted butadiene by alternate molecular stacking in the crystalline state
Tanaka, Toshihiro,Matsumoto, Akikazu
, p. 9676 - 9677 (2007/10/03)
We report the first synthesis of a disyndiotactic polymer through topochemical polymerization using di(4-methoxybenzyl)muconate as the 1,3-diene dicarboxylate monomer. It provides a tritactic polymer under photoirradiation in the crystalline state, as a r
