Abstract :In this study, a novel type of polymeric solid-solid phase change materials insert ignore into journalissuearticles values(SSPCMs); and Maleic anhydride insert ignore into journalissuearticles values(MA); modified poly insert ignore into journalissuearticles values(ethylene glycol); PEG. MAM-PEG polymers were synthesized from different moleculer weight PEG insert ignore into journalissuearticles values(Mw: 4000, 6000); .On the other hand two different catalyst system was used; para toluene sulfonic acid insert ignore into journalissuearticles values(PTSA); and 1,8-Diazabicyclo [5.4.0] undec-7-ene insert ignore into journalissuearticles values(DBU);.The PEG bound to the backbone of the polymers formed crystalline regions responsible from latent heat storage with reversible crystalline to amorphous phase transition as linked unit prevented total melting of the structure. Also MAM-PEG polyester polymers acid and hydroxyl values were determined for number of average molecular weight insert ignore into journalissuearticles values(Mn); and calculated as 36232 and 49020. Characterization and thermal properties of SSPCMs were performed by using fourier transform infrared insert ignore into journalissuearticles values(FT-IR); spectroscopy and differential scanning calorimetry insert ignore into journalissuearticles values(DSC); techniques mainly. DSC results showed that solid-solid transitions 36-54 °C temperature range and 163-153 Jg-1 enthalpy. As a result, MAM-PEG polymers were found potential for thermal energy storage insert ignore into journalissuearticles values(TES); applications.
