Abstract :
A study has been carried out on volume resistivity of low density polyethylene (LDPE) which is irradiated with an electron beam by using an electron beam accelerator. From the analysis of DSC, the crystalline melting point of the specimen irradiated with electron beam is lower than that of original specimen. It is confirmed that the volume resistivity increased as temperatures increase from 60[°C] to the crystalline melting point because of the defects of the solid structure and the formation of many trap centers by mean of electron beam irradiation, but decreased as temperatures go over the crystalline melting point because of the crystalline melting
