Effect of Electron Beam Irradiation on Electrical Conductivity of PVC (Poly Vinyl Chloride) was carried out. characteristics of PVC changes according to the dosage of electron beam irradiation. That is amorphous nature of PVC changes to crystalline and also conjugate double bond and free radicals are formed due to the degradation. The free radicals formed due to scission process in responsible at higher energy radiation. The electrical conductivity of polyvinyl chloride after irradiation slightly increases with electron beam radiation dose. It is due to increase in crystallinity in the polyvinyl chloride after electron beam irradiation and production of free radicals due to scission or crosslinking in PVC.
