Paper Abstract

The FT-IR spectra of Poly A film at 0.0,'Zffl to 100.0RH approached by dynamic equilibrium were measured according to the ascending and descending order of relative humidity. As compared with the static hydration the experimental phenomena and effects are similar in both processes. however, for the most obsorotion bands the dynamic hydration begin at a lower relative humidity and behave a faster and more even hydration rate than in the static case. The experiments also show that the hydration and dehydration process are irresvertible and the hydrating water could not be desorbed in low relative humidity. This indicates that the water molecules combined with Poly A have strong chemical bonding.
