| Abstract: | Viscosity, Infra-red, NMR spectral measurement technique, density measurement, and electrical conductivity were used to study the changes that occured during γ-radiolysis of Nylon 6. It was observed that it undergoes chain scission and crosslinking, but chain scission predominates over crosslinking in air irradiation. From melting temperature, density measurement, and the use of the Flory equation the enthalpy of fusion of Nylon 6 is 11.86 and 13.84 kJ/mol in an inert atmosphere and in air irradiation, respectively. The indirect effective band gap decreases and electrical conductivity increases when Nylon 6 is irradiated with γ-rays. |
