Effect of monomer concentration on the Size of Micron-Sized Polystyrene Particles produce by Dispersion Polymerization with tumbling system

In this study, we used a tumble system to produce different sizes of polystyrene microspheres of styrene with a steric stabilizer (PVP) and radical initiator (AIBN) in an ethanol/water medium. The effects of different parameters (styrene concentration) on the morphology polystyrene microspheres were studied. The analysis of optical and SEM micrographs showed that PS microspheres with different sizes could be prepared in alcohol/water medium when appropriate initiator and stabilizer concentrations were employed. In addition it was found that microsphere sizes decreased with increasing water content in the dispersion medium.
