中文摘要：

采用乳液聚合法以苯乙烯（St）为单体,十二烷基硫酸钠（SDS）为乳化剂,水/丙酮作为溶剂,芬顿试剂、在pH=3~4的弱酸性条件下作为引发剂,制备了粒径约为170nm的单分散聚苯乙烯（PS）微球。该工艺选用新型引发剂芬顿试剂,无需除氧,聚合时间短,操作简单,制备出的PS微球粒径可控,和传统工艺相比具有明显的优势。

英文摘要：

The monodisperse polystyrene microspheres were prepared by emulsion polymerization method,using styrene（St） as monomer,sodium lauryl sulfate（SDS） as emulgator,water/acetone as dispersion medium,and fenton oxidant（FeSO4/H2O2） as initiator at the condition of pH=3~4.It is shown that the average size of polystyrene microspheres which assembled by dip-drawing method were about 170nm under the experimental parameters.Comparing with traditional technology,the technique described above had some advantages such as no deoxygenation,controllable size,simple and quick polymerization process due to using a new initiator which has not been reported.
