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。

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。

Photo-Crosslinkable Gelatin Hydrogel: Versatile Materials for (High Resolution) Additive Manufacturing

Discussion of synthetic modifications to gelatin, improving the three-dimensional (3D) print resolution, and resulting material properties.

Biomacromolecules, 1(1), 31-38 (2001-11-17)
Dynamic shear oscillation measurements at small strain were used to characterize the viscoelastic properties and related differences in the molecular structure of hydrogels based on gelatin methacrylamide. Gelatin was derivatized with methacrylamide side groups and was subsequently cross-linked by radical

A PCL/hydrogel construct that would mimic the structural organization, biochemistry and anatomy of meniscus was engineered. The compressive (380 ± 40 kPa) and tensile modulus (18.2 ± 0.9 MPa) of the PCL scaffolds were increased significantly when constructs were printed with a shifted design and circumferential

Hydrogels are promising soft materials for the delivery of therapeutic cells and cargo molecules. Inspired by mussel adhesion chemistry, hydrogels based on catechol (Cat)-modified polysaccharides have been developed to enhance hydrogel-tissue interactions. However, due to the inevitable side reactions such
