Ai. Vilenskii et al., HIGH-ENERGY ION TRACKS IN POLYIMIDE .1. PROPERTIES OF POLYIMIDE IRRADIATED WITH HIGH-ENERGY IONS, High energy chemistry, 28(4), 1994, pp. 285-288
Properties of polyimide irradiated with high-energy Ar and Kr ions (en
ergies 40 and 210 MeV, respectively) are discussed. Irradiation result
ed in the degradation of imide rings followed by the formation of amid
o groups and crosslinks. Circular dichroism of the polyimide IR absorp
tion bands and the dependence of the chemical stability of the polymer
on ion fluences were studied.
