ESR Evidence of Growing Unsaturation in -Irradiated Poly (Vinyl Alcohol)
Abstract: AbstractFree radicals present in gamma irradiated PVAL subjected to different degrees oxidation are identified using ESR spectroscopy. The observed ESR spectra are analysed by computer simulations. Gamma irradiated PVAL immediately after irradiation possess ~CH2–CH–CH2~ type free radicals (I). Upon oxidation the free radicals transform to ~CH2–CH=CH–CH2~ (II) highly oxidized PVAL consist ~CH2–C=O (III) type free radicals. The results suggest that radical (I) is precursor to radicals (II) and (III). Oxidation …
