ABSTRACT = {ARGET ATRP of methyl acrylate (MA) with low concentration of air stable-CuBr<sub>2</sub> 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 (M<sub>w</sub>/M<sub>n</sub>
=1.1). Interestingly, we
found that the PEG has the reduction ability to CuBr<sub>2</sub>
 and could play as supplement reducing
agent cooperation with Me<sub>6</sub>
TREN to mediate ARGET ATRP. Reduction of Cu(II)Br<sub>2</sub>
 to Cu(I)Br by
different molecular weight PEG was proved by UV–visible spectroscopy. A.Q.-PEG with different
molecular weight have strong effects on polymerization rate and the polymerization can be
operated at suitable conditions where the use of catalyst concentration can decrease to 25 ppm
level.},
