In this paper, the methods to prepare polyalcohols mixtures were discussed. The phase change temperatures and phase change heats of monobasic, binary and triatomic systems consisting of neopentylglycol(NPG), pentaerythritol(PE) and trihytdroxy methyl-aminomethane(TAM) with different component were studied experimentally by differential scaning calorimeter(DSC). Feasibility of materials used in the building envelope was analyzed. Results can provide the basis for the application of solid-solid phase change materials in the building fields.
