Evaluation of Crystallinity in Poly (Vinyl Alcohol) and ...

the control and the oxidized PVA samples are given in Table I. An important observation made from Fig. 5is that in the initial stages of oxidation (i.e. up to a reaction period of 20min), the intensity of absorption band at 1141cm -1 reduces, but in the final stages of reaction this band becomes sharp. Fig. 6 shows a semi-log plot of X-ray ... ................
