【Abstract】 The seeded micro spheres of polystyrene(about 3 μm) were prepared by dispersion polymerization, and porous styrene divinybenzene copolymer micro spheres were prepared by extraction after polymerization. The particles of multi hollow structure were characterized by SEM photograph with detailed discussions made on the mechanism of porous formation and the effect of toluene on porous structure.更多还原
