| 摘 要： | 选用β-环糊精为稳定剂,以苯乙烯为原料、过硫酸钾为引发剂,采用无皂乳液聚合法制备单分散聚苯乙烯微球。利用扫描电镜对微球进行表征,研究了微球合成过程中稳定剂用量、苯乙烯单体用量及引发剂用量对微球粒径分布的影响。实验结果表明：适当地改变稳定剂用量、苯乙烯单体用量及引发剂用量可以得到不同粒径且单分散性良好的聚苯乙烯微球。

| Abstract: | Using styrene as raw material,potassium persulfate as an initiator and β-cyclodextrin as a stabilizer,polystyrene microspheres were successfully prepared by means of soap-free emulsion polymerization method.The microstructures were characterized with SEM,and the effects of the stabilizer dosage,the styrene monomer dosage and initiator dosage on the particle size distribution were studied.The results show that polystyrene microspheres with different particle sizes and good monodispersity were obtained by changing amount of stabilizer and the styrene monomer dosage and dosage of initiator appropriately. |
