Abstract: | The 1‐naphthylmethylammonium salts of not only (Z,Z)‐ but also (E,E)‐muconic acid were found to polymerize upon photoirradiation in the crystalline state to provide a stereoregular polymer in a high yield. The stereochemical structure of both polymers obtained from the monomers with different configurations was identical, i. e., a meso‐diisotactic‐trans‐2,5‐structure. The stereochemistry of the polymers obtained is discussed on the basis of the monomer configuration and the molecular packing in the crystals. |
