In this paper, the dielectric behavior of γ-irradiated polyether ketone with cardo group (PKK-C) was studied. It was found that the obvious change of dielectric behavior exists after irradiated at the certain dose (2.02 MGy). The temperature spectra of dielectric loss factor ε" within the range of 20—200℃ and the frequency spectra of dielectric coefficient ε′ in the range of 30 Hz—1 MHz have shown that ε′ increases from 3 to 5 and ε" increases from 5.4×10,-3, to 4.6×10,-1, for the irradiated PEK-C.
