用分散聚合方法制备单分散聚苯乙烯微球。用扫描电镜测定了微球粒径大小和分布随着介质溶解度的增大，微球的粒径先增大而后减小，引发剂浓度的提高导致微球粒径的增大和粒径分散系数的变大
Monodisperse polystyrene microspheres were prepared by dispersion polymerization. The particle size and distribution of microspheres were determined by scanning electron microscopy. With the increase of the solubility of the microspheres, the particle size of microspheres first increased and then decreased. The increase of initiator concentration resulted in the increase of particle size and the dispersion coefficient Bigger
