Notes:
Polysalicylide, a condensation product of acetylsalicylic acid, was irradiated with 60Co-γ-rays. Viscosity, end-group analysis, and ultraviolet (UV) spectral measurement technique, and electrical conductivity were used to study the changes that occurred during γ-radiolysis. It was observed that polysalicylide undergoes chain scission caused by weak links. The enthalpy of fusion is 16.0 and 13.4KJ/mol-1 repeat units of polysalicylide in air and N2, respectively. The indirect effective band gap decreased and electrical conductivity increased after irradiation.
