The coordination function of ionic liquids [N3MIM]Cl was prepared by the alkylation reaction of organic polyamines and 1-chloro-ethyl-3-methyl chloride ionic liquid [CeMIM]Cl using a microwave reactor. The functionalized ionic liquids can form catalytic system with CuBr

replacing traditional organic ligands

in atom transfer radical polymerization (ATRP) reaction where ionic liquids was used as reaction medium. The effects of reaction conditions on the yield of ionic liquids have been studied. The results showed that the reaction time was short with higher yield using the microwave reactor. The yield of product [N3MIM]Cl was 98.6% when the reactant ratio was 1.5:1

the reaction temperature was 75℃ and microwave reaction time was 3 h. Electrospray ionization mass spectrometry and IR were used to determine the structures of ionic liquids [N3MIM]Cl. The coordinated ionic liquid that would replace of organic ligand was used in the ATRP of MMA in ionic liquids. The results showed that: the coordination function of ionic liquid can increase the solubility of the catalyst in the ionic liquids

so that the transition metal catalyst is easily separated from the polymer product.
