摘要：

Pyridylmethanimine-based ligands are used in aqueous media at neutral pH for the efficient living radical polymerization of hydrophilic monomers. High conversions (>90%), good molecular weight control, and low polydispersities (M-w/M-n < 1.20) were obtained for the polymerization of monomethoxy-capped oligo(ethylene glycol) methacrylate at 20 <degrees>C; faster rates, reduced control, and higher polydispersities were obtained at elevated temperatures.
