| 摘 要： | 合成了聚氧化乙烯－聚对苯二甲酸乙二醇酯（PEO－PET）多嵌段共聚物，以红外光谱（RIR）、核磁共振谱图（NMR）对产物进行了结构表征，结果表明产物的组成与理论基本一致；利用差示扫描量效法研究了PEO－PET共聚物的热行为，发现共聚物中软段PEO与硬段PET的结晶性竞相互作用的影响。

| Abstract: | In this paper, Poly (ethylene oxide ) -poly (ethylene terephthalate) block copolymer was prepared. The structure of the copolytrier was characterized by FTIR and NMR. The composition of the copolyttier rusulted from FTlR and NMR analysis was consistent with the calculated results. The thermal behavior of the copolymer was investigated by DSC. It is found that the crpetality of PEo and that of PET have significant effect on each other. |
