Abstract

The objective of this article is to study an amorphous superabsorbent polymer, which is able to absorb up to 300 times its weight of water. Adsorption–desorption phenomena of water vapor on the polymer as a function of temperature showed a reversibility of the adsorption–desorption phenomena. The thermal stability of the polymer at atmospheric pressure was also studied. The kinetic study of the desorption phenomena of water vapor on the polymer according to certain physicochemical parameters was discussed. The results showed that the kinetic regime governing the desorption phenomena of water vapor on the polymer is a process limited by a mono-dimensional diffusion for low masses and by a three-dimensional diffusion for high masses.
