Abstract The samples of polypropylene (PP) have been irradiated with 120 MeV 64Cu9+ and 70 MeV 12C5+ion beams, with the fluence ranging from 1 × 1013 to 1 × 1011 ions/-cm–2. UV-VIS and FTIR techniques have beenused to study the chemical and optical properties of these irradiated polymers. UV spectra revealed that theoptical-gap energy decreases by 54 % with copper ion irradiation at the fluence of 1 × 1013 ions/cm2, whereasat the same fluence, carbon beam decreases the optical-gap energy by 20%. FTIR analysis of ion irradiatedsamples revealed the presence of –OH, C = O and C = C bonds. Alkyne formation has been observed only in thecase of copper ion irradiation.
