Abstract ARGET ATRP of methyl acrylate (MA) with low concentration of air stable-CuBr2 catalyst was
successfully carried out in green solvent polyethylene glycol (PEG) without any external reducing
agent.The polymerizations of MA proceeded in a well-controlled manner as evidenced by kinetic
studies, chain extension results, a linear increase of the molecular weights with the increasing
of monomer conversion. and narrow molecular weight distribution (Mw/Mn
=1.1). Interestingly, we
found that the PEG has the reduction ability to CuBr2
and could play as supplement reducing
agent cooperation with Me6
