| 摘 要： | 本文利用L-谷氨酸苄酯和L-赖氨酸苄酯分别与三光气反应合成N-羧基- L-谷氨酸g-苄酯环内酸酐(NCA)和N-羧基-L-赖氨酸g-苄酯环内酸酐,用三乙胺作为引发剂,引发NCA进行开环聚合,合成了聚谷氨酸苄酯与聚谷氨酸赖氨酸苄酯共聚物。利用核磁共振仪 (1H-NMR)、傅里叶变换红外光谱(FTIR)、凝胶渗透色谱(GPC)及X射线衍射仪(1D-WAXD)等方法对单体、聚合物的分子结构以及结晶性能进行了表征。

| Abstract: | In this article g-benzyl-L-glutamate N-carboxyanhydride (NCA) and g-benzyl-L-lysine NCA were synthesized by g-benzyl-L-glutamate and g-benzyl-L-lysine with triphosgen. Triethylamine is used as initiator to prepare PBLG and PBLG-co-PZLL via ring opening polymerization procedure. 1H nuclear magnetic resonance spectroscopy (1H-NMR), fourier transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), and 1D wide-angle X-ray diffraction (1D-WAXD) were used to characterize the molecular and crystalline structures of the prepared polypeptides. |
