Abstract: Analyzed is the effect of coupling agents on properties of polymeric PTC materials. It is found that the coupling agents J1 and J2 have better dispersion property than J3 at low temperature. The  opposite holds at high temperature. Moreover, the PTC intensity was enhanced and the NTC intensity was decreased by radiation crosslinking. These qualitative results were discussed analytically.
