Radiation induced modified polystyrene(PS) has been investigated by vibrational (Fourier transform infrared) spectroscopy. FTIR spectrum of unmodified PS has shown absorption bands around 3050cm-1,2550 cm-1,1245cm-1,1580 cm-1,1465cm-1,1370 cm-1,1060cm-1,1028 cm-1,751 cm-1 positions. On irradiation a change in intensity of the absorption bands is observed together with a band shift Reasons for these changes are explained based on chemical changes induced by gamma irradiation.

Key words: PS(polystyrene), FTIR (Fourier transform infrared) spectroscopy, Gamma irradiation
