| Abstract: | The properties of radicals formed on irradiating long chain monomers in urea canal complexes were studied by ESR and related to the results of post-polymerzation. The initiating radicals (CH3-?HCOOR) were trapped in canal complexes as a result of γ-irradiation at relatively high temperature such as 25° and the radicals converted to propagating radicals (～CH2-?HOOR0 on heating to 70°. The temperature dependence of radical concentration was followed and the decay curves corresponded well with the results of post-polymerization. |
