PURPOSE:To provide a thermal energy storage material which can retain an excellent thermal energy storage performance over a long period of time, by dispersing a thermal energy storage agent consisting of Na2SO4, water, sodium borate decahydrate and polysodium acrylate in a curved unsaturated polyester resin. CONSTITUTION:130-190pts.wt. water, 3-50pts.wt. sodium borate decahydrate and 5-50pts.wt. polysodium acrylate (0.5% aq. soln. thereof having a viscosity of 3,000-50,000cPs at 20 deg.C) are blended with 100pts.wt. Na2SO4 to obtain a thermal energy storage agent. 2-20pts.wt. catalyst such as benzoyl peroxide, 0.05- 2.0pts.wt. accelerator such as cobalt naphthenate and said thermal energy storage agent are added to 100pts.wt. unsaturated polyester resin. The mixture is polymerized and cured.
