| 摘 要： | 用固定化酶Novozyme435(NV435)催化2,2-二羟甲基丁酸(BHB)与ε-己内酯(ε-CL)开环缩聚得到端基中一端带有一个羧基,另一端带有多个羟基的超支化共聚酯。利用核磁共振分析(NMR)、傅立叶红外(FTIR)、凝胶渗透色谱仪(GPC)对超支化聚合物进行结构表征,用扫描电子显微镜(SEM)分析了聚合物的表面形貌。

| Abstract: | The hyperbranched aliphatic polyester P（ε-CL）was synthesized by means of novozyme 435 -catalyzed ring- o- pening （ROP） polymerization of BHB 2,2-bis （hydroxymethyl） butyric acid ]. The chains ended with hydroxyl of P（ε-CL）. The copolymer was confirmed by NMR, FTIR and GPC. The surface morphology of the hyperbranched polymers was determined by SEM. |
