DIELECTRICP ROPERTIES POLYMETHYLMETHACRYLATE STRUCTURE SUBJECTED TO RADIATION EXPOSURE
It is shown that the laserirradiation of the electrical properties of polymethylmethacrylategoes through significant changes. It was found that the relaxation time of the electrical parameters of the irradiated samples of polymethylmethacrylate is 80±10 hours, which corresponds to an electrets state.
