Abstract

In this work ,some electrical properties ( such as electrical conductivity ) and optical properties(such as refractive index ) of synthetic rubber solution in toluene with concentration ) ml gm (0.5 were measured at 30 co after irradiation the polymer with different doses of gamma ray by using 60 Co source with energy 1.25 MeV. The results show exchange effects of polymer-solvent molecules and polymer polymer macromolecules appear on increment in the value of refractive index, reflectance and Browster angle with the increasing gamma radiation dose , in contrast the electrical conductivity , molar conductivity and critical angle with increasing given dose .
