Study of the properties of PVC/ABS blends

The aim of this work is to study the properties of PVC and ABS blends. For that, variable compositions of blends from 0 to 100 wt% were realized. Their physico-chemical properties were determined by differential scanning calorimetric analysis (DSC) and Fourier transform infra-red spectroscopy (FTIR). The variation of the mechanical properties such as tensile behaviour, impact resistance and hardness was studied according to the composition of blend . The influence of a plasticizer introduced at a level of 30 wt% on the same mechanical properties has been considered.
