| 抄録: | ESR spectra of free radicals formed from isoprene, 1, 3-pentadiene and 2, 3-dimethyl-l, 3-butadiene were studied at -196°C. Free radicals were formed by several ways, i.e. electron-irradiation, reaction with HO· and CH₃· radicals and ultraviolet-irradiation at -196°C. The structure of trapped free radicals formed by electron-irradiation are quite different from that of radicals formed by radical reactions. The mechanism of radiation-induced solid state polymerization is discussed. It is concluded that the trapped free radical formed by radiation is not the propagating radical but an inactive radical end which is formed in the ionic propagation process initiated by an ion-radical. |
