| 摘 要： | 研究了高真空熔融缩聚法制备聚癸二酸酐-聚乙二醇(PSA-PEG)共聚物,采用红外光谱(FTIR)、凝胶渗透色谱(GPC)对制备出来的PSA-PEG共聚物进行了结构表征,并进行了共聚物性能的测定.将癸二酸预聚物与不同分子量的PEG共聚,研究了聚合物结构组成与性能之间的关系,并通过改进实验方法,得到分子量分布较窄的共聚物(PDI:1.10),使制备出的PSA-PEG6000共聚物数均分子量Mn由原来的7291增加到12281.

| Abstract: | The method of synthesizing poly(sebacic anhydride-co-ethylene glycol) copolymers via melt-polycondensation under high vacuum was investigated. The copolymers were then characterized by IR and GPC, and their properties were determined. In addition, Different copolymers were synthesized by varying the molecular weight of the PEG. The properties of the copolymers, including their molecular weight, polydispersity index, melting point, and degradation ability were investigated. The molecular weight of the copolymers was increased by improving the previous method via polycondensation of PSA oligomer and PEG 6000. |
