General description
甲基丙烯酸乙酯（EMA）是聚合物工业领域常用的单体。它是甲基丙烯酸和乙醇的酯，是一种具有特征气味的无色液体。EMA广泛用于生产各种聚合物，如聚甲基丙烯酸甲酯（PMMA）、聚丙烯酸乙酯（PEA）和乙烯-EMA（EE）。这些聚合物在各个领域都有应用，包括医疗植入装置、包装、纸张涂料、纺织涂料、乳液聚合物和塑料。甲基丙烯酸乙酯是一种易聚合单体，用于某些类型的丙烯酸树脂。其中存在的单甲醚羟基醌是一种防止聚合的抑制剂。
Application
甲基丙烯酸乙酯 (EMA) 可在以下应用中用作单体：
- 合成苯乙烯-甲基丙烯酸甲酯或苯乙烯-甲基丙烯酸乙酯人造纳米胶乳，用于制备药物释放膜。
- 用于牙科用增材制造的甲基丙烯酸酯树脂的生产。
- 用于全固态锂电池的星形嵌段共聚物电解质的合成。
- 用于半导体纳米粒子基质的共聚物的合成，这对于光电应用中使用的量子点-共聚物复合材料形成稳定的基质至关重要。也可用于制备糯玉米上的EMA共聚物 淀粉和羟丙基淀粉，这些共聚物的潜在应用是作为压缩非崩解骨架片的赋形剂。它可用于研究丙烯酸正丁酯和 EMA 与臭氧在气相中的反应。

Molecular interaction between alcohols (1-propanol, 1-butanol, s-butanol, t-butanol, 1-pentanol, 1-heptanol, 1-octanol and 1-decanol) with ethyl methacrylate has been studied in n-heptane, CCl(4) and benzene at 298K using FTIR spectroscopic and dielectric methods. The result obtained from both the methods indicates
