摘　　要：采用分散聚合法制备出了平均粒径为3.0μm的窄分布线型聚苯乙烯微球,并在此基础上改进聚合工艺,制备出了平均粒径约为3.0μm的窄分布交联聚苯乙烯微球。对两种类型聚苯乙烯微球进行形貌及粒径、红外光谱、差示扫描量热法(DSC)分析和耐溶剂性实验,结果表明交联聚苯乙烯微球与线型聚苯乙烯微球相比,其球形度较差,粒径分布较宽,但耐热性和耐溶剂性较好。In the present paper,narrow size distribution linear polystyrene microspheres with average size of3.0μm are prepared by dispersion polymerization.Through modifying polymerization technological process,narrow size distribution crosslinked polystyrene microspheres with average size of about3.0μm areprepared.These two kinds of polystyrene microspheres are compared in some properties including morphology and size analysis,FITR,DSC and solvent-resistant experiment.The results showe that crosslinked polystyrene microspheres have poorer sphericity,wider size distribution,better heat-resistant and solvent-resistant properties than linear polystyrene microspheres.
