A water soluble monomer, oligo(ethylene glycol) monomethyl ether methacrylate (OEOMA), was successfully polymerized in an inverse microemulsion system via the activator generated by electron transfer atom transfer radical polymerization (AGET ATRP) technique. A series of hydrophilic polymer particles containing well-defined water-soluble polymers polyOEOMA with relatively narrow molecular weight distribution (Mw/Mn < 1.5) were obtained. The effect of changing various reaction parameters,including the amount and type of reducing agents used for the generation of activators in the AGET ATRP, on the level of control over the polymerization process and final particle size was studied. Through a rational selection of polymerization conditions, stable colloidal particles with a readily tunable size, ranging from ca. 40 to 200 nm, were prepared.
