Abstract

Abstract

Gamma irradiation effect of methacrylamide-ethyl methacrylate (MA-EMA) copolymer has been investigated by electron spin resonance (ESR) and Fourier Transform infrared (FTIR) spectroscopic techniques. The ESR spectrum observed for gamma irradiated MA-EMA copolymer has shown resolved hyperfine (hf) pattern at lower temperatures (77K) while at higher temperatures the spectrum is appeared to be broadened. Fourier Transform Infrared spectra of pure and gamma irradiated MA-EMA copolymer have been recorded for the copolymer irradiated to different radiation doses to ascertain chemical changes induced by gamma irradiation. The variation in intensity of 3420, 1660,1250, 1160 and 1020 cm-1 absorption bands is observed, which are attributed cleavage of ester, amide groups on irradiation.
