Abstract

Highly monodispersed polystyrene (PS) nanoparticles were prepared via the reversible addition fragmentation transfer (RAFT) living radical emulsion polymerization technique using a sur-iniferter, 4-(2-hydroxyethyl)piperazine-1-carbodithioicacid benzylether (HPCB). The monodispersed nanoparticles were colored by various methods, namely random and block copolymeriztion, the end group reaction and the adsorption method. For the coloration of the block and random copolymer monodispersed nanoparticles, a color pre-monomer was previously synthesized with a vinyl functional site. Dynamic light scattering and scanning electron microscopy were the main tools used to analyze the size and distribution of the prepared nanoparticles. Copyright © 2006 John Wiley & Sons, Ltd.
