The photopolymerization reactivity and the polymer structure control of several benzylammonium sorbates as the 1, 3-diene monomers in the crystalline state are described. The polymerization of the 4-methyl-substituted benzylammonium derivative proceeds to give a stereoregular polymer in the crystalline state under UV irradiation, similar to naphthylmethylammonium sorbate. We have also succeeded in the synthesis of a ladder polymer by topochemical polymerization of p-xylylenediammonium disorbate as the bifunctional monomer under similar conditions. The polymerization mechanism and the stereochemical structure of the resulting polymers are discussed based on the results of the X-ray single crystal structure analysis as well as IR, NMR, and ESR spectroscopic studies. We have demonstrated a unique two-dimensional polymer synthesis by topochemical polymerization via a radical chain mechanism based on polymer crystal engineering, which is useful for the control and design of the polymerization reactivity and the polymer chain and crystal structures.
