  Abstract

In this study, polystyrene hollow microspheres were prepared via optimized purifying steps for the reuse of waste polystyrene. PS/PVA double layered hollow microspheres were prepared using the multiple emulsion (W1/O/W2) method with recycled polystyrene. The sonication treatment at the first stage of W1/O emulsion formation was very important factor of control of particle size and its distirbution. When sonication was treated for 20 seconds, the average particle size and distribution were 1.35 μm and 0.8 μm ~2.8μm, respectively. The double layered hollow microspheres that have smaller and uniformed particle size distribution were manufactured when gelatin or Tween 80 was used as surfactants in the W2 phase.
