摘要：

Water molecules sorbed in pure poly(vinyl alcohol) and poly(vinyl pyrrolidone), as well as in their blends is found to be only partially crystallizable. The fraction of non-crystalizable water is shown to vary with the blend composition. Such variation is explained by the newly proposed Tg-regulation effect when the swollen blend materials is cooled down. A part of the sorbed water cannot crystallize due to the fact that during cooling the amorphous polmer-water phase is frozen before the water crystallization temperature is reached.
