摘　　要：从苯甲醛甘油缩醛出发,经聚乙二醇单甲醚端基改性,通过一系列反应合成了含有双羟基并带有MPEG相变单元的新型单体,并通过逐步聚合方法合成了一种新型固-固相变储能材料。通过红外、核磁、DSC表征了制备的新型相变材料的组成结构和相变行为。结果表明该相转变材料拥有较好的相转变特性。In this paper,beginning from Benzaldehyde glycerol acetals,through the end-groups modification of MPEG,a novel monomer with double carboxyl and phase change unit of MPEG was synthesized via a series of reaction.And then a novel solid-solid phase change storage materials was synthesized via polymerization step by step.The composition,structure and phase change behavior of the copolymer were researched via FI-IR spectra,~1H NMR spectra,DSC curve.The results show that the phase change storage material has an excellent phase change properties.
