Effects of Gases on Irradiated Polyvinyl Chloride as Studied by Electron Spin Resonance

Journal Article · · Journal of Chemical Physics
DOI:https://doi.org/10.1063/1.1730701· OSTI ID:4192184

The radicals produced by gamma irradiation of polyvinyl chloride powder in various gases and in vacuum are observed by electron spin resonance. Different patterns are observed for the irradiation in vacuum, air, and sulfur dioxide. No electron spin resonance absorption is obtained by the irradiation in nitrogen oxide, halogens, and hydrogen sulfide. The recombination reaction velocity of the radical produced in vacuum is measured at different temperatures to get the activation energy 38 kcal/mole.
