PREPARATION OF VARIOUS MULTI HOLLOW SHAPE PARTICLES VIA DUAL-SEEDED DISPERSION POLYMERIZATION

In this work, the effect of various polymerization conditions on the shape of the particles produced by dual-seeded dispersion polymerization (DSDP) of 2-ethylhexyl methacrylate with polystyrene (PS) and poly(methyl methacrylate) (PMMA) seed particles in the presence of saturatedhydrocarbon droplets in a polar media was discussed. It was observed that with changing the affinity between the hydrocarbon and PS seed particles, second monomer type multi hollow particles with a variety of shapes can be produced. Moreover, the experimental results showed that shape of the particles which was produced by shaking is more multi hollow than the shape of the particles which was obtained from tumbling.
