%X The effects of testing temperature on notch impact strength,fractographic fea-tures and fracture surface roughness of PVC have been studied.The results show that there areminimum value of notch impact strength and fracture surface roughness of PVC with changingtesting temperature.Notch impact strength is controlled by the area of real fracture surface.Thefracture surface roughness depends on both micro plastic deformation and crack branching.Thefringe lines and stratification due to crack branching are easily observed on lower temperatureimpact fracture surface.
