Effect of Gamma-Ray and temperature on the viscosity of polystyrene

الملخص EN

In this research the effect of gamma rays had been studied on the reduced viscosity and intrinsic viscosity and Huggins constant of polystyrene (PS) solution in the solvent benzene, by the determination of the average molecular weight of (PS) using Mark - Houwink – Sakurada equation depending on the values of intrinsic viscosity.

The effect of temperature in the range (25-60)C on the reduced viscosity had been studied too.

The results showed that (PS) undergoes crosslinking after irradiation in air with gamma rays emitted from Cs137 source and degradation with increasing temperature.
