4,4′-亚甲基二(N,N-二缩水甘油基苯胺),英語:4,4′-Methylenebis(N,N-diglycidylaniline),简称4-DGA、TGDDM等,[7]是一种四官能度的苯胺型环氧树脂单体,可与多种酸酐固化剂(如甲基四氢邻苯二甲酸酐、甲基六氢邻苯二甲酸酐、顺丁烯二酸酐、戊二酸酐等)发生开环聚合,形成高度交联的热固性网络。TGDDM不仅能提供用于调节网络玻璃化温度的刚性苯环,还提供叔胺基团,能够催化体系固化和酯交换反应。[8]TGDDM因含有四个非线性官能团,且固化物交联密度高,与传统的线性双酚A型环氧树脂相比,具有黏度更低、流动性和加工性更好、热机械性能优异等特点,广泛应用于航空航天、电子电气等领域。[9]
合成
[编辑]TGDDM可通过环氧氯丙烷与4,4′-二氨基二苯基甲烷反应,形成中间产物氯醇,并在NaOH中反应制得。[10]
