一般描述

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。

应用

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。

Here, we report our studies on photoresponsive poly(meth)acrylates containing azobenzene groups connected to a polymer backbone via a short methylene linker. A series of side-chain azobenzene polymers was synthesized via the atom transfer radical polymerization (ATRP) technique using several catalytic
