摘　　要：炔基与叠氮基的1,3-偶极环加成反应作为点击化学的精髓,反应高效,条件温和。通过它与控制自由基聚合结合,为制备多种拓扑结构嵌段共聚物提供了新途径,所得嵌段共聚物纯度高,分子量分布较窄。本文就1,3-偶极环加成点击反应与3种控制自由基聚合方法相结合在制备线型及非线型嵌段共聚物方面所取得的成就加以综述,并对今后的发展方向做了展望。1,3-dipolar cycloaddition resulted from alkynyl and azido is cream of the crop in click chemistry.This reaction is high-efficiency and its reaction condition is moderate.It offers a new way to prepare block copolymer with various well-defined structures by combining 1,3-dipolar cycloaddition with controlled radical polymerization.The prepared block copolymer is with high purity and narrow molecular weight distribution.In this paper,the facile combination of 1,3-dipolar cycloaddition with three kinds of controlled radical polymerization on preparing linear and nonlinear block copolymer was reviewed.Moreover,the further development direction was prospected.
