文摘

In this work, a novel phase change material poly(decaglycerol-co-ethylene glycol) [P(DG-co-EG)] copolymer was prepared by free-radical solution polymerization based on two macromonomers, polyethylene glycol acrylate (PEGA) and polydecaglycerol acrylate (PDGA), which were synthesized via acryloyl chloride modification. The results showed that the crystallization enthalpy of P(DG-co-EG) achieved to 141.3 J/g, and its soaking time increased up to 15 min with the increase of molar ratios of PEGA to PDGA:TGA results indicated that P(DG-co-EG) degraded in two steps and its maximum degradation rate was at 420 ¡ãC.
