中文摘要：

随着人们环保意识的增强以及绿色化学概念的普及，离子液体由于其蒸汽压极低、不可燃、不挥发、稳定性好、电导率高、电化学窗口较宽、可设计性强等独特的优势，在化学催化、反应介质、萃取、电化学、新材料等众多领域受到研究者们的广泛关注。本文主要从离子液体作为溶剂、配体、单体、以及回收利用催化剂四方面简述了离子液体在原子转移自由基聚合中的应用。

英文摘要：

As increase of people＇s awareness of environmental protection and population of the concept of green chemistry, the application of ionic liquids in chemical catalysis, reaction medium, extraction, electrochemistry, novel materials and many areas have attracted researchers ＇ widespread attentions and investigations. Because ionic liquids have unique physical and chemical properties, such as very low vapor pressure, nonflammable, non-volatile, good stability, high conductivity, wide electrochemical w}ndow, strong designability and so on. In this article, we reviewed the application of ionic liquids in atom transfer radical polymerization from the aspect of ionic liquid used as solvent, ligand, monomer and used to recover catalysts.
