Abstract
An amphiphilic graft copolymer comprising poly(ethylene oxide) (PEG) grafts was synthesised and characterised. It was used to stabilise the emulsion polymerisation of St or BuA. The effectiveness of this PEG-containing graft copolymer in stabilising St/BuA emulsion polymerisation was studied. Finally, stable dispersions of polystyrene microspheres were used as templates, and polystyrene microspheres were coated with Fe3O4 by in situ reaction of Fe3+ and Fe2+ in the presence of OH−. No additional treatments were needed in the process.
