Abstract The progress in the synthesis of block copolymers such as hydrophobic block copolymers, amphiphilic block copolymers, functional block copolymers, fluorinated block copolymers, silicon- containing block copolymers and thermoplastic elastomers by atom transfer radical polymerization (ATRP) was introduced. The methods included (1) strict ATRP, which means block copolymers were generated from macroinitiators synthesized by ATRP， (2) mechanistic transformations, which means ATRP macroinitiators were prepared by other mechanism such as cationic, anionic, conventional radical and step growth polymerizations or a simple organic transformation.
Key words Atom transfer radical polymerization, Block copolymer

摘要 介绍了近年来利用原子转移自由基聚合(ATRP)技术合成各类嵌段共聚物(包括油溶性嵌段共聚物、两亲嵌段共聚物，含功能单元的嵌段共聚物、含氟嵌段共聚物、含硅嵌段共聚物和热塑性弹性体等)的研究进展。采用ATRP合成嵌段共聚物的方法包括：(1)全ATRP法，也就是指用ATRP技术合成的聚合物作为大分子引发剂引发其它单体的ATRP反应；(2)ATRP与其它机理间的转换，包括ATRP与阴离子、阳离子、普通自由基聚合间的转换或是通过简单的化学反应在聚合物末端引入活性基团进一步引发单体的ATRP。
