| 摘 要： | 超支化聚酰胺-酯(HPAE)含有类似于球形状的分子结构和大量活性端基,因而在胶粘剂、涂料、流变改性剂及染料等领域中具有潜在的应用前景。以均苯四甲酸酐(PMDA)和二乙醇胺(DEA)为原料,合成出一种中心核(By);然后以2,2-二羟甲基丙酸(DMPA)为AB2单体,将其与By进行熔融缩聚反应,制成水溶性的HPAE。结果表明:By的数均相对分子质量(Mn)、重均相对分子质量(Mw)分别为1 697、1 889 g/mol,Mw/Mn=1.11,说明其相对分子质量分布较窄;HPAE分子骨架中含有强极性酰胺键、弱极性酯键和大量强极性羟基,易溶于水;水溶性HPAE的支化度为0.47,其Mn、Mw分别为2 195、3 676 g/mol,Mw/Mn=1.67。合成原料易得、工艺简单,适合大量制备超支化聚合物。
