一般說明

丙烯酸丁酯通常用作单体或结构单元,用于生产各种类型的聚合物,包括丙烯酸酯和甲基丙烯酸酯聚合物。它还与其他单体结合使用,以获得所得聚合物的特定性能。这些聚合物可用于广泛的应用,例如油漆和涂料、纺织品、粘合剂、锂离子电池、执行器以及生物医学设备和包装材料。在丙烯酸丁酯的聚合中,最常用的抑制剂是单甲醚氢醌(MEHQ)。通常添加少量(10-60 ppm),以阻止聚合过程中发生不良副反应,确保可控且高质量的聚合物形成。它还可以通过与可能引发聚合的自由基反应,有效提高丙烯酸丁酯的储存稳定性。丙烯酸丁酯与含有乙烯基的苯并恶嗪进行自由基共聚,得到共聚物。已有报道关于由膦基咪唑盐介导的芳基溴代与丙烯酸丁酯的偶联反应。已有介绍关于在CuBr/4,4′-二(5-壬基)-2,2′-二吡啶的催化下,ATRP催化苯乙烯与丙烯酸丁酯的共聚反应。

應用

丙烯酸丁酯(BA)可用作:
  • 锂离子电池中的电解质添加剂,可改善其低温性能。电解质中添加BA可显着改善电池的低温性能,包括增强的离子电导率和提高的倍率性能。
  • 用于合成形状记忆聚合物网络的单体,其中包含磁性纳米粒子,适用于各种应用,包括执行器和生物医学设备。
  • 用于制备具有固有可拉伸特性的聚合物半导体的单体。这种聚合物材料用作场效应晶体管应用中的组件。丙烯酸丁酯用于制备:
    • 聚(丙烯酸丁酯)粒子。
    • 聚丙烯酸丁酯-b-丙烯酸嵌段共聚物。
    • 两亲性带电双嵌段共聚物聚(丙烯酸丁酯)-b-聚(丙烯酸)。
    • 在CuIBr/4,4′-二(5-壬基)-2,2′-双吡啶(催化剂)存在下,共聚物(丙烯酸丁酯)通过原子转移自由基聚合(ATRP)合成丙烯酸丁酯。

Monomers for ophthalmic use aim for purity, reliability, and comfort, driving innovation for affordable contact lenses.

Heck反应是烯烃与芳基或乙烯基卤化物(或三氟甲磺酸酯)之间的钯催化交叉偶联反应,用于生成取代的烯烃。

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
