Degradation and stabilization of some polymers has been investigated by electron spin resonance (ESR) spectroscopy and FTIR (Fourier transform infrared) spectroscopy technique. As an example polypropylene powder has been irradiated with gamma ray and radiation effects has been investigated by recording ESR spectra. PP is mixed with stabilizer and resultant samples have also been irradiated with gamma rays and ESR spectra are also recorded. Reduction in intensity of ESR spectra suggest the stabilization effect of stabilizers degradation effects are evidenced in FTIR spectra.

Key words: Degradation, ESR, FTIR, Free radical, stabilization, gamma irradiation.
