摘要

介绍了一种以癸二酸、乙二醇和甘油为原料合成可降解脂肪族聚酯的方法，并利用红外光谱、光电子能谱、示差扫描量热法、X 射线衍射和力学测试等方法对聚酯的性质进行了研究。结果显示，产物表现出典型的高弹性，随着原料中癸二酸/乙二醇的比值增加，产物的弹性模量呈增加趋势，微观结构由局部有序向无序转变。产物具有良好的生物降解能力，37℃下在含猪胰脂肪酶的磷酸缓冲溶液里72h 失重率在6.1%~14.4%之间。

Abstract

A novel series of biodegradable polyester were synthesized via esterification of sebacic acid

glycol and glycerol.Fourier transform infrared spectrum (FTIR)

X-ray photoelectron spectroscopy (XPS)

Differential scanning calorimetry (DSC)

X-ray diffraction analysis (XRD) and mechanical tests were performed to examine the properties of polyester.Results showed that the products exhibited typical high elasticity.As the ratio of sebacic acid and glycol in raw material increased

the modulus of the products also increased and the microstructure changed from partly order to disorder.The products had good biodegradability

and the weight losses were between 6.1-14.4% after degradation in the phosphate buffer solution with porcine pancreas lipase at 37℃ for 72h.
