- Abstract
The 13C CP/MAS NMR spectra of polystyrene were recorded for un-irradiated samples and for samples exposed to a 8989 Gy dose of gamma radiation. The most intense peaks of unirradiated sample appear at 145 and 127 ppm and are assigned to non-protonated and protonated aromatic carbons, respectively. The gamma irradiation leads to an important decay of T1ρ relaxation time corresponding to aromatic and methylene-methine functional groups.
