Free radicals in γ‐irradiated poly‐α‐methylstyrene

Free radicals in γ‐irradiated poly‐α‐methylstyrene

Electron spin resonance (ESR) spectra were observed at −160°C and at room temperature for γ‐irradiated poly‐α‐methylstyrene. The spectrum observed at room temperature has been attributed to the radical species while that at −160°C results from the same radical and superposition of the spectrum due t...

description Electron spin resonance (ESR) spectra were observed at −160°C and at room temperature for γ‐irradiated poly‐α‐methylstyrene. The spectrum observed at room temperature has been attributed to the radical species while that at −160°C results from the same radical and superposition of the spectrum due to the radical ĊH2‐C(CH3)(C6H5)‐. The radicals which are stable at room temperature could be used to graft vinyl acetate.
