<P>PROBLEM TO BE SOLVED: To provide a polymer latent heat storage material whose temperature region to be used, that is, a melting point (and a freezing point) can be freely selected and basic properties are unchanged, and which can be applied to a heat storage system without changing components thereof, and to provide a heat storage capsule using the same. <P>SOLUTION: This polymer is prepared by controlling the molecular weight thereof by manipulating the degree of polymerization in the process of polymerization reaction so that the melting point and the freezing point are set to a temperature suitable for any heat storage system in which the polymer is used. The polymer latent heat storage material is composed of the above-described polymer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
