Abstract
IT has been suggested that the kinetics of water sorption by cellulose as well as the sorption kinetics of other small penetrant molecule–polymer systems in the region where the polymer behaves like a glass can be explained in terms of a coupled diffusion–relaxation mechanism1–3. The sorption kinetics have been studied with the original regenerated cellulose modified by a moderate degree of formaldehyde induced cross-linking.
