acid)s, which are synthesized by topochemical polymerization and subsequent solid-state hydrolysis, are used as the organichost materials for intercalation. We describe the reaction behavior and layered structure of intercalation compounds using stereoregular poly(muconic acid)s and n-alkylamines as host and guest, respectively. The packing structure of the guest alkylamines was determined by X-ray diffractions

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 result of the alternate molecular stacking in a column formed in the crystals with aid of weak hydrogen bonds such as CH/pi and CH...O intermolecular interactions.
