PURPOSE:An inexpensive and nontoxic thermal energy storage material, obtained by adding a phenolic compound of an amine to a molded article of an intermolecularly crosslinked crystalline polyolefin (copolymer) without corroding a metallic material nor causing supercooling nor phase separation, and utilizing the latent heat of melting. CONSTITUTION:A polyolefin thermal energy storage material obtained by molding a particularly highly crystalline polyolefin, e.g. crystalline polyethylene (PE) or polypropylene (PP), or a copolymer thereof into the form of a sphere, cylinder, plate or round tubing, crosslinking intermolecularly the resultant molded article by the ion, water crosslinking, vulcanization, oxide or radiation method, etc., and adding a phenolic compound or amine, e.g. cresol or phenylenediamine, thereto. |
