摘要
Topochemical polymerization of the (E,E)-diene derivative was demonstrated. The 1-naphthylmethylammonium salt of (E,E)-muconic and sorbic acids polymerized in the crystalline state and provided a stereoregular polymer. NMR spectra of the resulting muconate polymers showed a meso-diisotactic-trans-2-5-structure, irrespective of the configurations of the monomers. On the other hand, based on powder X-ray diffraction profiles, during topochemical polymerization, the mode and rate of the reactions are determined by the molecular packing of the substrates, suggesting that geometrical isomers should be regarded as completely different compounds rather than homologous monomers.
