Abstract: Polymethyl methacrylate (PMMA) foils were irradiated under vacuum with 70 MeV C5+ ions to the fluences of 3.1×1011, 3.7×1012, 1.8×1013, 5.6×1013 and 1.2×1014 ions cm-2. Ion induced optical, chemical and structural modifications were studied by ultraviolet, visible (UV-Vis) and Fourier Transform Infrared (FTIR) spectroscopy and X-ray diffractometer (XRD). PMMA suffers degradation under irradiation, UV-Vis data show the increase of optical absorbance and the shift of absorption edge from the UV towards visible with the increase of the fluences, attributing to the formation of conjugated system of bonds. The intensity of infrared bands and characteristics of different chemical functional groups are found to decrease with Swift Heavy Ion (SHI). Crystallite size of irradiated sample shows a decrease of 8%
