Application

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。

General description

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。
