超支化聚酯的合成及表征
Synthesis and Characterization of the Hyperbranched Polyester
【摘要】 以双酚酸[4,4-双(4-羟基苯基)戊酸]为主要原料,采取熔融缩聚的方法制得了超支化聚酯,利用傅立叶变换红外、端基分析法、乌氏黏度计及热重分析对产物等测试技术进行了初步表征,结果表明,超支化聚酯表现为较低的特性黏度、良好的溶解性和热稳定性.
【Abstract】 The synthesis method of hyperbranched polyester was presented based upon diphenolic acid (DPA). The process of polymerization was characterized by FTIR. The number average molar mass was measured by analysis of end_group. The product exhibits relative thermal stability as analyzed by thermogravimetry in an air atmosphere, and show low viscosity and high solubility.
