Abstract

Abstract 4, 4′-Bis (chloroacetyl) diphenylether was synthesized and its polycrystal form was produced. This polycrystal sample was irradiated by gamma rays (60 Co) for 72 h. The ESR method was used to observe formation of free radical on the sample. ESR signal was not recorded from the non-irradiated sample, but the irradiated polycrystal sample exhibited complex ESR spectra. The measurements were carried out in the temperature range of ...
