Abstract

Ambient temp. atom transfer radical polymn. (ATRP) of Me acrylate (MA), Me methacrylate (MMA) and styrene (Sty) in the presence of polar solvents (DMSO: dimethylformamide: DMF and acetonitrile: MeCN) with a mixed transition metal catalyst system (Fe(0) as initial activator and CuBr2/Me6TREN complex as deactivator) provides a rapid synthesis of polymers with very low polydispersity (PDI) values and predetd. mol. wts. The polymethylacrylate (PMA) prepd. using this novel approach contains the Br-terminated chain ends (functionality ∼100%) and can be successfully used for block copolymer synthesis (as demonstrated on the chain extension expt. performed using the PMA-Br macroinitiator). The key elementary reactions involved in this novel ATRP system and some preliminary mechanistic aspects of the process are also discussed. [on SciFinder(R)]
