Methyl acrylate polymerization catalyzed by Cu(0) is carried out in toluene using a range of alcohols and phenol as polar/coordinating additives. These additives promote disproportionation of Cu(I) to Cu(0), the proposed active species in single electron transfer living radical polymerization (SET-LRP), and Cu(II) whilst toluene maintains solubility of the reagents and products. In this study, we investigated the effect of these additives and also the purity of the Cu(0) used in the reactions using online characterization techniques.
