Hydrophilic, regenerated cellulose ยฎlms are characterized by certain adsorption properties. These investigations were aimed at determining to what extent the moisture content of a ยฎlm might decide its barrier capacity against water vapour. The experimental materials were an unlacquered regenerated c

## Abstract The purpose of this article is to elucidate the effect of integral sorption of moisture on gas permeation in glassy hydrophilic polymers. The oxygen and the simultaneous moisture sorption into various hydroxypropyl methylcellulose (HPMC) films were measured under a wide range of relativ
Moisture adsorption isotherms of Tarhana were determined at 25 ยฐC and 35ยฐC. As the temperature increased, the adsorbed moisture content decreased at water activities between 0.2 and 0.9. The experimental sorption data obtained were applied to the Halsey, Harkins-Jura, Smith, BET and Freundlich isoth
