一般說明

N,N,N′,N′′,N′′-五甲基二乙烯三胺(PMDETA)是一种胺基单体化合物,在聚合物领域发挥着关键作用,特别是在合成TRP-热敏聚合物方面。PMDETA在各种聚合反应中起着多功能配体或催化剂的作用。它与过渡金属形成配合物,用于生产特殊聚合物、嵌段共聚物和具有改性性质的聚合物。这些聚合物广泛应用于各个行业,包括热塑性塑料、弹性体和涂料。当加入聚合物结果时,PMDETA有助于赋予最终产物的热响应行为,使溶解性、构象或其他物理性能随温度变化而发生可逆变化。这使得PMDETA在TRP合成和设计中成为了个有价值的组成部分,TRP在药物输送系统、智能材料和响应涂层等领域中得到应用。

應用

N,N,N′,N′′,N′′ 五甲基二乙烯三胺可用作:
  • 合成多功能硅丙烯酸酯预聚合物的催化剂,用于紫外光固化涂料。
  • 合成聚丙烯酰胺水凝胶的多功能引发剂和交联剂。它改善了水凝胶的机械性能,如韧性和弹性,同时不影响其生物相容性。
  • 三亚甲基碳酸酯开环聚合(ROP)中的有机催化剂。与金属催化剂相比,该催化剂在反应后易于去除。
  • 通过原子转移自由基聚合(ATRP)技术合成一系列侧链偶氮苯聚(甲基)丙烯酸酯。
  • 一种用于生长聚苯乙烯链的引发剂,以制备聚烯烃-聚苯乙烯共聚物。
