一般描述

马来酸酐（MA）属于一类被称为环状二羧酸酐的单体。它通常用于聚合反应，以生产各种类型的聚合物，如聚（马来酸酐）（PMA）、马来酸酐基树脂和马来酸酐-丁二烯共聚物（MABS）等。这些基于MA的聚合物在各种领域中都有应用，包括聚合物共混物和涂层、环氧树脂、半导体器件、二次电池、锂离子电池、树脂薄膜、玻璃纤维、涂层、包装、水处理和药物输送系统。此外，MA可以接枝到其他聚合物上，以增强其性能和与其他材料的兼容性。接枝聚合物可应用于汽车、包装和建筑行业。由于马来酸酐具有反应性双键和反应性酸酐基团，因此马来酸酐也可在各种抗菌聚合物的开发中用作电子受体单体。[1][2][3][4][5]

马来酸的结构由四个碳分子以及两端的羧酸基团组成，中心碳原子之间有一个双键。马来酸酐在其环状分子中具有五个原子，不饱和键在引发剂存在下经历自由基聚合。

应用

马来酸酐可用作单体：
  • 在高密度聚乙烯（HDPE）的接枝过程中，通过单体微胶囊化技术，可以将增强的功能和改进的性能引入聚合物中，用于功能涂层、膜或表面处理、粘合剂和涂层。
  • 在聚乳酸（PLA）的功能化中，并在天然纤维生物复合材料中充当偶联剂。功能化改善了PLA和天然纤维之间的相容性和界面粘附，从而增强了所得到的生物复合材料的机械性能并扩大了其应用范围。
  • 马来酸酐可用于合成不饱和聚酯树脂和用作合成重要产品的反应物，例如农业化学品、润滑剂添加剂，和食品酸化剂。
