一般描述

甲基丙烯酸酐在36.6oC下发生共聚反应，产生其聚合物。它可以通过使用脱水剂由相应的酸直接制备，也可以由酸的钠盐与相应的酰氯化合物反应而间接制备。
由甲基丙烯酰胺水凝胶制备的明胶具有高储能模量。

应用

甲基丙烯酸酐可用作前体，用于合成生物可再生树脂，应用于复合材料应用。例如，它可用于制备大豆油和丁香酚基树脂体系。这种树脂具有高热稳定性和良好的机械性能，适用于拉挤工艺中的基质。

它可作为甲基丙烯酸化剂，用于制备高性能木质素基热固性材料。

它也可用作起始剂：
  • 以通过共聚反应合成对pH值敏感的甲基丙烯酸酯硫酸软骨素水凝胶。这些水凝胶可用于给药系统。
  • 通过Iniferter介导的聚合反应，获得具有更高分子内交联密度的分子内交联高分子（ICM）。
