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 window

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.
