<P>PROBLEM TO BE SOLVED: To provide a water-based heat storage material consisting of water as a major component, wherein water does not easily leak out from a broken container under a compression lord. <P>SOLUTION: The water-based heat storage material comprises a hydrogel prepared by polymerizing sodium αβ-unsaturated carboxylate and NN'-methylenebisacrylamide in the presence of a redox polymerization initiator and water and is characterized by at most 80% deformation rate of the above hydrogel under a compression lord. The water-based heat storage material comprises a hydrogel prepared by polymerizing sodium αβ-unsaturated carboxylate and NN'-methylenebisacrylamide in the presence of sodium chloride and water and is characterized by at most 60% deformation rate of the above hydrogel under a compression lord. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
