Effect of GAMMA Rays on some types of viscosity and optical properties for polycarbonate in chloroform at room temperature

Abstract

Some types of viscosity for polycarbonate aqueous solution in Chloroform with concentration of 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5 and 5% were determined for two kinds of samples, first non-radiated & the second, irradiated with  source for a rate of 508 rad/min for 20 minutes. The results show that the values of shear, relative, specific & reduced viscosity were increased with increasing the concentration of  polycarbonate in chloroform, Also the properties which had been determined in this work, increased after radiation, this could be attributed to penetration of ionizing radiation in the polymer structure & cross linking the chains.
