It is found in this paper that the dielectric behavior of polyetherketone with cardo group (PEK- C) irradiated at a dose of 2.02 MGy has an obvious change. For the irradiated PEK-C, both the temperature spectrum of dielectric loss factor ( ε ") within a range of 20- 200 "C and the frequency spectrum of dielectric coefficient ( ε ') in a range of 30 Hz-1 MHz show that ε " and ε ' increase from 5.4×10^-3 to 4.6×10^-1 and from 3 to 5, respectively.
