| 摘 要：以丁二酸酐和二乙醇胺为起始原料经加成反应合成新型AB2型单体,在溶液中采用“准 一步法”自缩聚反应合成超支化聚(酰胺-酯),使用傅里叶变换红外光谱、乌式粘度计、差热-热重联 用分析仪等测试分析超支化酰胺类聚合物的结构、粘度及热性能,红外光谱图分析进一步证实了聚合 物的超支化结构。实验表明封端剂对超支化聚合物的粘度有较大影响,封端产品粘度在0．019- 0．057 dL／g范围之间,而未封端产品粘度为0．146 dL／g。热分析中,超支化聚(酰胺-酯)的Td(热分 解温度)为316．3℃,Tg(玻璃态转化温度)为270℃;结果表明,超支化聚(酰胺-酯)具有较低的比浓 对数粘度、良好的溶解性和热稳定性等特点。 |

| Abstract：A sort of AB2 intermediate was synthesized by using diethanolanmine and butanedioic anhydride as initial materials, and a quasi-one-step method was used to synthesize hyperbranched poly (amide-ester). Fourier transform infrared spectrometer. Wushi viscisity meter and DSC-TGA analyzer were used to synthesize the structure, viscosity and thermol stability of hyperbranched poly (amide-ester). The hyperbranched structure of polymer was validated by the IR spectra. End-capped reagent had a great effect on viscos... |
