Abstract

Abstract In this comparative study it has been tried to find a correlation between the thermal and mechanical stabilities of some γ-irradiated polymers. Among various mechanical properties evaluated, the best correlation was found between the toughness (energy to break point) and the time required for 10% weight loss (isothermally). Among three polymers irradiated up to 100 kGy in the form of thin films, the best fit was observed to be for PMMA while PVC and PP has shown poorer correlation.
