Monodispersed OEGMA/St polymeric particles were prepared through soap‐free emulsion polymerization, then surface modification was conducted by atom transfer radical polymerization (ATRP), and nano‐size hairy shell of OEGMA/St particles were obtained. By hydrolysis, the grafting chains of the hairy particles were successfully cut down from the core particles. Through gel permeation chromatography (GPC) and transmission electron microscopy (TEM) measurements, the density of grafting chains was calculated. Experimental results showed that the hairy shell on the surface of the particles could dramatically improve the particles dispersibility in organic solvents. Copyright © 2006 John Wiley & Sons, Ltd.
