Abstract

Radiation behavior of Acrylonitrile AMPS copolymer has been investigated by Electron Spin Resonance (ESR), Fourier Transform Infrared (FTIR) techniques. Temperature dependent ESR studies indicate that free radicals responsible for irradiated copolymer decay at around 100°C. Presence of macro-radicals and polyene radicals is detected. FTIR spectra of copolymer of unirradiated and irradiated are compared and chemical groups influenced by gamma irradiation are identified. The studies suggest that chain cleavage occur either on AMPS part or AN part depending on the co-monomers. DSC thermograms indicate that chemical transformations occur at higher temperatures.

 

Keywords: AN AMPS copolymer, gamma radiation, ESR spectrum, FTIR spectrum, DSC spectrum, free radicals
