[en] This paper report on the decisive effect that solvent has on the atom transfer radical polymerization of methyl metacrylate (MMA) at low temperature. In buta-none and in the presence of a copper(I)/bipyridine com-plex the polymerization is controlled and the molecular weight distribution is narrow, at 0°C and even lower. This control is maintained when ε-caprolactone (CL) is substi-tuted for butanone. The use of this polymerizable solvent together with a novel dual initiator, 2-hydroxyethyl. 2'-methyl-2'bromopropionate, is an efficient strategy to pre pare PMMA-b-PCL diblock polymers in a one-pot process.
