Abstract

The radiation chemical yields for losses of ether and carbonate ester bonds in poly(allyl diglycol carbonate) (PADC) have been determined by means of Fourier transform infrared (FT-IR) spectrometry for He (2.3 and 20 MeV) ions, as well as C (1.10, 1.25, and 1.39 GeV) and Fe (20.8 and 22.8 GeV) ions. 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.
