Abstract
A porous and transparent hydrated gel is prepared from a poly(vinyl alcohol) solution in a mixed solvent consisting of water and an water-miscible organic solvent. Upon cooling the poly(vinyl alcohol) solution below room temperature, a gel is formed as a consequence of crystallization of poly(vinyl alcohol) molecules. Exchange of the organic solvent included in the gel with water produces a hydrated gel of poly(vinyl alcohol) which has a high tensile strength, a high water content, and a high light transmittance.
