Chemical characterization of PMMA after E-beam irradiation. a) Fourier transform infrared (FT-IR) spectra, b) Thermal Gravimetric analysis (TGA), and c) Differential scanning calorimetry (DSC) plots of PMMA before and after 25 or 50 kGy irradiation. Increasing C=C and O–H and reducing C=O and C–O peaks intensities suggest that 50 kGy has a more prominent effect on the chemical structure of the PMMA. Irradiated samples have two decomposition stages compared to one in non-irradiated PMMA, with varying T10, T50, Tmax, (TGA) and Tg (DSC), suggesting the chain scission and crosslinking in the 25 and 50 kGy, respectively.
