Abstract: Starch was reacted with polyethylene terephthalate polyethylene glycol (PET-PEG) copolymer using hexamethylenediisocyanate as a coupling agent in order to prepare new PET-PEG/ST copolymers. The obtained PET-PEG/ST was characterized by FTIR and 1HNMR spectroscopy, thermal analysis, and the water absorption and biodegradable tests. The results show that starch was attached to PET-PEG via couple reaction in the presence of hexamethylenediisocyanate. As compared to PETPEG, PET-PEG/ST has avariable thermal stability with decreasing melting temperature. PET-PEG/ST has degraded in aqueous solution with different pH under different levels, and the degradation rate of PET-PEG/ST in aqueous solution under different pH values from big to small order as follows: alkaline solution,acidic solution,neutral solution. PET-PEG/ST also tends to degrade in biologically active environments like amylase.

Key words: Starch, PET-PEG, Modification, Biodegradation, Coupling reaction

摘要：  使用淀粉改性对苯二甲酸乙二醇酯 - 聚乙二醇共聚物( P E T - P E G) , 以六亚甲基二异氰酸酯为偶联剂,
制备了一系列含淀粉的P E T - P E G共聚物( P E T - P E G / S T) , 并对其进行了结构表征和性质分析。实验结果表明, 淀
粉与P E T - P E G发生了偶联反应, 随着淀粉质量分数的增加, 共聚物的热稳定性有所降低。P E T - P E G / S T具有良好
的生物降解性, 能在淀粉酶作用下快速降解, 在不同p H条件下的降解速率由大到小的顺序为: 碱性、 酸性、 中性。

关键词: 淀粉, P E T - P E G, 改性, 生物降解, 偶合反应
