Abstract

The ultrafast and additive-free triazolinedione-click reaction with electron rich (di)enes is a powerful method for the ultrafast ligation of polymer segments. A versatile method is described for the introduction of clickable TAD end groups in various polymer segments, using reversible addition-fragmentation chain transfer polymerization. These triazolinedione-functionalized prepolymers were subsequently used for macromolecular functionalization with a low molecular weight diene and block copolymer synthesis of different types within seconds, at ambient conditions, through the coupling with diene-functionalized polymers such as poly(ethylene glycol) and poly(isobornyl acrylate).

摘要

富电子（二）烯烃的超快且无添加剂的三唑啉二酮点击反应是聚合物链段超快连接的一种有效方法。本文描述了一种通用方法，通过可逆加成-断裂链转移聚合，在各种聚合物链段中引入可点击的三唑啉二酮端基。这些三唑啉二酮功能化的预聚物随后用于与低分子量二烯烃进行大分子功能化，并在环境条件下，通过与二烯功能化聚合物（如聚乙二醇和聚（异冰片基丙烯酸酯））偶联，在几秒钟内合成不同类型的嵌段共聚物。
