Effect Time Factor on Some Physical Properties for Polystyrene irradiation and Dissolved in Toluene


We have studied in our research the effects of both gamma- rays and time factor on some physics properties as a function of changing some physical properties with the speed of ultrasound for Polystyrene dissolved in the toluene at (30 ± 3oC) temperature by existence the presence of air to maintain the stability of the physics properties of polymeric materials exposed to the radiation.
