General description
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。
Application
- 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。
