Abstract: | Crosslinked polystyrene microspheres of a diameter of the order of more than 2 μm and a narrow particle diameter distribution were synthesized by emulsifier-free emulsion polymerization. The dependence of various parameters such as an electrolyte (NaCl), an initiator (K2S2O8), the phase volume ratio, the reaction temperature and time on the diameter and the particle size distribution has been discussed. |
