The Effect of Mixed Ligands on the Polymerization Rate of SET-LRP in Aqueous Solution

Abstract The mixed-ligand effect is investigated in single electron transfer-living radical polymerization (SET-LRP) of OEOMA in aqueous solution for the first time. Mediated by equimolar tris(2-aminoethyl)amine (TREN) and tris(dimethylaminoethyl)amine (Me6-TREN), SET-LRP exhibits the highest polymerization rate while maintaining living characteristics. The higher concentration of self-assembled micellar particles formed by amphiphilic initiator and monomer in aqueous solution under the influence of mixed ligands may be considered as one of factors for the mixed-ligand effect.
