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.
