Influence of Gamma Radiation on physicochemical properties of Polyacrylamide in ethylene glycol at room temperatures

Abstract

The aim of this work is to study the effect of gamma radiation on some
rheological and optical properties of Polyacrylamide in ethylene glycol. The
polymer irradiated with gamma rays to 127 and 254 (rad/min) for 10 minutes on
a disk shape samples.
The rheological parameters (shear, Relative, specific, reduced, and Intrinsic
viscosity), Average viscosity number molecular weight and Effective molecular
radius, in addition, the optical parameters Absorbance, refractive index, Molar
absorption coefficient, Reflectivity, Coefficient of finesse and Specific
reflectance were studded.
The obtained results show decrease in (shear-relative-specific-reduced)
viscosities, average viscosity molecular weight, original viscosity on other hand
there is disparity in the values of effective molecular radius, absorption
coefficient, refractive index, reflectivity coefficient of finesse, and specific
reflectance as the dose increases.
The results show that radiation dose has effective influence on polymer
chemical structure therefore its properties will be a function of radiation dose.
