title: First disyndiotactic polymer from a 1,4-disubstituted butadiene by alternate molecular stacking in the crystalline state.
abstract: 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.
