摘要：

Millimeter-sized nonspherical polystyrene particles were synthesized by using a type of lamelliform organic montmorillonite as modifier in suspension polymerization. The structure of montmorillonite was characterized by scanning electron microscope(SEM)and X-ray diffraction(XRD). The distribution of montmorillonite in polystyrene particles was investigated by energy dispersive spectrometry(EDS)and SEM. Effects of the content of montmorillonite, mass ratio of oil to water and dosage of dispersing agent on the morphology of the particles were discussed, and the particle formation mechanism was also analyzed. The results show that the particles shift from ellipsoid to spindle with the increase of montmorillonite content;the spindle-shaped particles flatten into dish-like ones with increasing mass ratio of oil to water;when the dosage of dispersing agent is raised to a certain amount, nonspherical particles transform into spherical ones. © 2016, Editorial Board of Journal of Tianjin University(Science and Technology).
