Abstract
The influence of sorbed water on the IR spectrum of dextran has been studied as a function of the degree of hydration of the polymer. By analyzing the pattern of spectral changes it has been established that the water molecules are present in the bound state. Features of the specific interactions of water molecules with different active groups in the polymeric matrix are described. It has been found that the tendency to form large clusters of water is low in hydrated dextran and is shown only at vapor pressures close to saturated.
