Notes:
Polycondensation of diethyl chelidonate (DEC), which contains an electron-accepting γ-pyrone nucleus, with hexamethylenediamine (HMD) takes place easily even at room temperature to form a corresponding polyamide. Since DEC was expected to form a charge transfer complex with an electron-donating compound such as polyvinylcarbazole (PVK), the polycondensation of DEC with diamines was carried out in the presence of PVK as a matrix. It was found that the rate of the polycondensation of DEC with diamines in dioxane was enhanced either by the presence of PVK or by the irradiation with ultraviolet (UV) light. Moreover, the polycondensation of DEC with HMD in the presence of PVK was accelerated by the UV irradiation, probably owing to the transfer of light energy.
