Single-Electron Transfer Living Radical Polymerization (SET-LRP) is a versatile technique for the ultrafast synthesis of vinyl polymers at ambient temperature. The outcome of the polymerization is dependent on the choice of solvent and ligand. The most important consideration is the retention of polymeric chain-end functionality. The SET-LRP of methyl acrylate (MA) initiated by methyl 2-bromopropionate (MBP) and mediated by Me6-TREN ligand was performed in DMSO and acetonitrile (MeCN) and the effect of solvent on kinetics and bromine chain end functionality were investigated. The SET-LRP of MA initiated by MBP was performed in DMSO solvent mediated by Me6-TREN and TREN ligands. The products were characterized by 1H NMR and MALDI-TOF spectroscopy both before and after functionalization of the bromine chain-end, showing the perfect retention of functionality at 100% conversion using each ligand.
