Poly(vinyl alcohol) (PVA) film was prepared through heterogeneous saponification of poly(vinyl acetate) (PVAc) film for the first time. To prepare saponified PVA film, the effect of time on degree of saponification at particular saponification conditions was studied. The different values of degree of saponification had found depended on the time. Optical microscopy was used to characterize the saponified PVA film surface morphology and property and found unusual grained morphology. The conversion of PVAc film to PVA film was measured using proton nuclear magnetic resonance spectrometer, X-ray diffraction measurement, differential scanning calorimetry, Fourier transform infrared spectroscopy and contact angle.
