Abstract
The absorption of water or moisture by solid polymers may be one of important phenomena in pure and applied polymer science. Therefore, the behaviors of water absorbed by a variety of polymers have been investigated by several physicochemical methods. In most cases, however, water is absorbed only in amorphous part, and thus the structure of water at the molecular level is not always definite. As for linear poly (ethylenimine) [poly(EI)], we found two distinct crystalline hydrates, in which water exists stoichiometrically as “water of crystallization”, and it was confirmed by the X-ray structure analyses that the formation of the hydrates is responsible for the remarkably hygroscopic nature of this crystalline polymer.
