“点击”反应在制备环状聚合物中的应用
摘要
Cyclic polymer is a kind of new polymeric material, which exhibits unique properties compared with linear polymers and has broad application prospect. However, the synthesis method is intricate because of its inherent complex structures. Click reactions, which coined by Sharpless, with the characteristic of high efficient, reliable and high selectivity and have been used as a new synthetic method of topological polymers. Living radical polymerization, such as atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer polymerization (RAFT) and nitroxide-mediated polymerization (NMP), can effectively control the polymerization and polymer structures. The combination of these two methods makes the synthesis of cyclic polymers easier. In this review, we briefly summarize the applications of click chemistry, click chemistry and living radical polymerization, click chemistry and other methods in the synthesis of cyclic polymers in the last few years. The combined click reaction and the above techniques are believed to play a positive role in the design and synthesis of functional cyclic polymers.
