ESR spectra of irradiated methacrylamide (MA) –2–acrylamido, 2-methyl propane sulphonic acid (MA AMPS) copolymer have been recorded in the temperature range of 300 410 K. The observed spectral features have been interpreted in terms of line intensities, line width and spread of the spectra as observed against temperature. Spectral areas and line widths are calculated by integration methods. The observed changes in intensity and line widths are related to radiation induced changes in MA AMPS copolymer.
