The atom transfer radical polymerization (ATRP) of N-isopropylacrylamide (NIPAAm) conducted in pure water at low temperature (4 °C) proceeds in a controlled fashion (Mn/Mw ≤ 1.2) to near quantitative conversion. Different initiators, ligands, copper halides and ratios of copper (I) to copper (II) were investigated to enhance the control and reduce the termination. The reaction proceeds with a very fast kinetics and a high amount of Cu(II) is needed to slow down the polymerization. The generated polymers were successfully chain extended suggesting that well defined and complex architectures can be obtained.
