Radiation stability of Polypropylene blended with Polyethylene and Polystyrene at sterilizing dose

The properties of Polypropylene (PP) are severely deteriorated when exposed to gamma ray [1]. Stabilization of PP may be achieved through blendingwith high radiation resistance polymers such as polyethylene (PE) or polystyrene (PS) [2]. In this work we studied the radiation stability of PP blended with 5 and 15% PE and PS, accompanied by compatibiliser and heat stabilizer
