An experimental study comparing radiation-induced degradation of poly(methacrylates) from ultraviolet, gamma-ray (/sup 60/Co), and electron-beam irradiation is presented. Analytical techniques used include mass spectroscopy, low-temperature electron paramagnetic resonance, and infrared spectrometry. The poly(methacrylate) polymers investigated are poly(methyl methacrylate) (PMMA), poly(t-butyl methacrylate) (PBMA), poly(methacrylic acid) (PMA), and poly(methacrylic anhydride) (PMA AN). All are shown to exhibit scission of the main chains and removal of the side groups when irradiated. 11 figures.
