一般說明

甲基丙烯酸酐是一种有机化合物,来源于甲基丙烯酸,属于丙烯酸类。它主要用作聚合物的单体,特别是聚(甲基丙烯酸)及其共聚物的生产中。由于其优异的化学和热稳定性,这些聚合物在广泛的行业中应用,包括生物可再生树脂、pH敏感水凝胶、热固性树脂、涂料、胶粘剂和塑料。在甲基丙烯酸酐的聚合过程中,最常用的抑制剂是Topanol A。通常以小量(2000 ppm)添加,以阻止在聚合过程中不良的副反应,确保受控和高质量的聚合物形成。

應用

甲基丙烯酸酐可用作合成以下材料的起始物:
  • 通过共聚反应合成甲基丙烯酰化软骨素硫酸盐pH敏感水凝胶。这些水凝胶可用于药物传递系统。
  • 高性能木质素基热固性树脂。
  • 凝胶聚合物电解质,然后与阴极集成以形成高性能锂离子电池。
甲基丙烯酸酐也可用作前体,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。该树脂具有较高的热稳定性和良好的机械性能,使其成为拉挤工艺的合适基体。
