Abstract

For hydrated poly(vinyl acetate) (PVAc), a series of Fourier-transform infrared (FTIR) spectra were obtained by the subtraction procedure. The relationship between the integral intensity of the O-H stretching bands in the spectra and water contents showed that water molecules absorbed in PVAc associate with each other gradually to form isolated clusters and/or microdomains as the value of water contents reached 1.40 weight percent. Significantly, not only the peak positions and absorbances of relating bands (such as C equals 0, C-O, O-CH) with ester group, but also those of C-H bands in PVAc were affected by the hydration.
