Description

The shape of EPR spectrum and constants characterizing the quantity of stabilized free radicals were found to change during γ-irradiation of industrial polymethylmethacrylate (PMMA) and its copolymers both without and with stress (all-round compression and tensile stress). The peculiarities of radiation damage were attributed to the size of regions of local excitations arising due to energy release from cooperative recombination of radicals
