Abstract: Amphiphilic magnetic microspheres ranging in diameter from 5 to 100 μm were prepared by dispersion copolymerization of styrene and poly(ethylene oxide) vinylbenzyl (PEO-VB) macromonomer (MPEO) in the presence of Fe3O4 magnetic fluid. The effects of various polymerization parameters on the average particle size were systematically investigated. The average particle size was found to increase with increasing styrene concentration and initiator concentration. It also increased with decreasing stabilizer concentration and molecular weight of MPEO. The content of the hydroxyl groups localized in the microspheres ranged from 0.01 to 0.2 mmo1 g-1.
