Water vapor sorption isotherms of cotton cellulose and B pattern starch preparations, potato starch, corn amylose, amylomaize, and retrograded potato starch, were determined at 5 and 25°C. The crystallinity fraction of these materials equilibrated with water vapor at various partial pressures was determined by x‐ray diffraction. The thermodynamic functions of adsorption were calculated, and B.E.T. constants were determined.
