Iron-mediated AGET ATRP of Styrene and Methyl Methacrylate Using Ascorbic Acid Sodium Salt as Reducing Agent
Atom transfer radical polymerization of styrene (St) and methyl methacrylate (MMA) in bulk and in different solvents using activators generated by electron transfer (AGET ATRP) were investigated in the presence of a limited amount of air using FeCl
3
·6H
2
O as the catalyst
ascorbic acid sodium salt (AsAc-Na) as the reducing agent
and a cheap and commercially available tetrabutylammonium bromide (TBABr) as the ligand. It was found that polymerization in THF resulted in shorter induction period than that in bulk and in toluene for AGET ATRP of St
while referring
to AGET ATRP of MMA
polymerization in THF showed three advantages compared with that in bulk and toluene: 1) shortening the induction period
2) enhancing the polymerization rate and 3) having better controllability. The living features of the obtained polymers were verified by chain end analysis and chain-extension experiments.
