The crystalline fraction of γ‐irradiated semicrystalline iron polymethacrylate was determined by X‐ray diffraction analysis. In particular, the changes in the crystallinity index (CI) of the polymer as a function of the received dose (10–95 kGy) were studied and correlated with the parameters obtained by Mössbauer spectroscopy. We also analyzed the thermal degradation of the iron polymethacrylate in a sample with a maximum of crystallinity by employing the thermoanalytical techniques TGA and DSC. © 1999 John Wiley & Sons, Inc.
