%X The micron-grade PMMA microspheres with narrow size distribution were prepared by dispersion polymerization.The mechanism of the dispersion polymerization was discussed.The factors influencing both the size and the size distribution of the microspheres including initial concentrations of the initiator,the monomer,the stabilizer,the polarity of the medium and the reaction conditions were studied.The results indicated that the size and the size distribution of microspheres both increased with initial concentrations of the initiator and the monomer.Increasing the amount of the stabilizer decreased the size and narrowed the size distribution of microspheres.Other factors such as the polarity of the medium and the reaction temperature had great influences too.By controlling these factors,the desired-size monodisperse microspheres could be obtained.
