AbstractA series of well-defined double-hydrophilic graft copolymers, consisting of poly(N-isopropylacrylamide)-b-poly(ethyl acrylate) (PNIPAM-b-PEA) backbone and poly(2-(dimethylamino)ethyl acrylate) (PDMAEA) side chains, were synthesized by the combination of single-electron-transfer living radical polymerization (SET-LRP) and atom-transfer radical polymerization (ATRP). PNIPAM-b-PEA backbone was first prepared by sequential SET-LRP of N-isopropylacrylamide and 2-hydroxyethyl acrylate at 25 degrees C using CuCl/tris(2-(dimethylamino)ethyl)amine as catalytic system followed by the transformation into the macroinitiator by treating the pendant hydroxyls with 2-chloropropionyl chloride. The final graft copolymers with narrow molecular weight distributions were synthesized by ATRP of 2-(dimethylamino)ethyl acrylate initiated by the macroinitiator at 40 degrees C using CuCl/tris(2-(dimethylamino)ethyl)-amine as catalytic system via the grafting-from strategy. These copolymers were employed to prepare stable colloidal gold nanoparticles with controlled size in aqueous solution without any external reducing agent. The morphology and size of the nanoparticles were affected by the length of PDMAEA side chains, pH value, and the feed ratio of the graft copolymer to HAuCl4. (C) 2009 Wiley Periodicals, Inc.
