Chemical modification along ion tracks in Poly (allyl diglycol carbonate), PADC, films has been studied by means of Fourier transform infrared (FT-IR) spectrometry, which has exposed to protons and heavy ions in air. Chemical damage parameters, namely, radial size of the track core, in which the considered chemical groups are lost, damage density, which is the number of losses of considered functional groups per unit length of tracks, and radiation chemical yields, G values, for each group are evaluated as a function of the stopping power. The radiation chemical yields are higher at lower stopping powers for each ion and greater with increasing charge at the same stopping powers. Secondary electrons with higher energy should play a significant role to increase the yields by producing damage at a relatively distant place from the ion trajectories.
