Abstract

Many of the applications require sterilization by gamma radiation. When polymeric materials are submitted to gamma radiation, changes are observed on their molecular structure. Poly (vinyl chloride) (PVC) plasticized with DOP is one of the major bulk polymers which is widely consumed in various applications.

In this study, the effect of gamma irradiation up to 50 KGy on mechanical properties (tensile strength, elongation at break and Young’s modulus) and the changes induced in the thermal analysis and morphology was investigated. The results revealed that the gamma irradiation affected considerably the PVC plasticized properties at 50 KGy. This degradation is due to the chain scission, which caused a reduction in the average molecular mass and cross-linking rate on one hand.
