“…27 Among living radical polymerizations, ATRP is attractive because of the rapid and reversible exchange between low concentrations of growing radicals and dormant species. 28 ATRP for the PS-b-PVP diblock copolymer was carried out with a procedure reported in the literature. 24,25 The first step, which produced PS-Br, involved the homopolymerization of styrene in bulk at 1108C for 5 h in the presence of MBP, CuCl, and HMTETA.…”

In this work, silver nanoparticles were synthesized with an amphiphilic diblock copolymer, polystyrene-block-poly(1-vinyl-2-pyrrolidone) (PS-b-PVP), as a template film. First, microphase-separated amphiphilic PSb-PVP (70 : 30 wt %) was synthesized through atom transfer radical polymerization. The self-assembled block copolymer film was used to template the growth of silver nanoparticles by the introduction of a silver trifluoromethanesulfonate precursor and an ultraviolet irradiation process. The in situ formation of silver nanoparticles with an average size of 4-6 nm within the block copolymer template film was confirmed with transmission electron microscopy, ultraviolet-visible spectroscopy, and wide-angle X-ray scattering. Fourier transform infrared spectroscopy also demonstrated the selective incorporation and in situ formation of silver nanoparticles within the hydrophilic poly(1-vinyl-2-pyrrolidone) domains, which were mostly due to the stronger interaction strength of the silver with the carbonyl oxygens of poly(1-vinyl-2-pyrrolidone) in the block copolymer. This work provides a simple route for the in situ synthesis of silver nanoparticles within a polymer film.

“…Therefore, much attention has paid to finding effective initiators. Thus far, many kinds of organic compounds have been found to use as effective initiators in a variety of polymerizations catalyzed by transition metals, such as haloalkanes,2, 4–6 allyl halides,7 haloalkylbenzene,8–11 haloketones,12–14 haloesters,15–21 haloamides,22, 23 halonitriles,24–26 sulfonyl chlorides,27–32 N ‐chlorosulfonamides,33 and so forth.…”

N‐Bromosuccinimide (NBS) was used as the initiator in the atom transfer radical polymerizations of styrene (St) and methyl methacrylate (MMA). The NBS/CuBr/bipyridine (bpy) system shows good controllability for both polymerizations and yields polymers with polydispersity indexes ranging from 1.18 to 1.25 for St and 1.14 to 1.41 for MMA, depending on the conditions used. The end‐group analysis of poly(MMA) and polystyrene indicated the polymerization is initiated by the succinimidyl radicals formed from the redox reaction of NBS with CuBr/bpy. © 2004 Wiley Periodicals, Inc.

“…In our laboratory a novel bifunctional initiator for the ATRP was developed on the basis of ethylene bis(chlorophenyl acetate) (ECPA) 14) . The initiating alkyl chloride species is activated by both an a-phenyl and an a-alkoxycarbonyl group; thus, styrene and acrylate type monomers are initiated with high efficiency.…”
