Abstract:The synthesis of Ag particles stabilized poly (N,N′‐methylene bisacrylamide N‐aminoethyl piperazine) (MBA‐AEPZ) and poly(N,N′‐dodecyl diacrylamide N‐aminoethyl piperazine) (MDA‐AEPZ) was reported. The effects of hyperbranched polymer structures and hyperbranched polymer concentrations were studied on the size and size distribution of Ag particles, which were determined from the UV plasmon absorption band and transmission electronmicroscopic analyses. The data show that slight change (10.3 and 9.7 nm) and large change on particle size (3.9 and ~ 200 nm) were observed with increase in concentrations of poly(MBA‐AEPZ) and poly(MDA‐AEPZ) at the same M:D, respectively. The difference is explained in terms of a mechanism of structure‐dependent stabilization. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
