摘要
可逆加成-断裂链转移(RAFT)聚合作为一种新型活性自由基聚合,由于其具有单体适用面广、操作条件温和、实施聚合的方法多——本体、溶液、乳液、悬浮聚合均可的优点已经在分子设计方面取得了广泛的应用。星形聚合物作为一种特殊结构的聚合物,由于其具有较低的结晶度、较小的流体动力学体积等独特的性质,越来越引起研究者的重视。本文综述了近几年来采用RAFT法合成星形聚合物的研究进展。根据合成星形聚合物所用的RAFT多官能团试剂种类,对RAFT法合成星形聚合物的反应进行了分类。
As a new living radical polymerization, reversible addition-fragmentation chain transfer （RAFT） polymerization has lots of advantages, such as a wide range of monomers, a mild reaction condition. And RAFT polymerization can proceed in bulk, solution, emulsion and suspension polymerization. So RAFT polymerization has exhibited wide applications in molecular design. Due to their unique characters, such as low crystallinity, smaller volume of fluid dynamics, star polymers as a special structure polymer have attracted more and more attention from researchers. This review deals with recent progress in RAFT polymerization in synthesizing star polymer. And Reactions are classified by muhifunction RAFT agent in synthesizing star polymer.
