英文摘要	Monodispersed polystyrene (PS) microspheres were synthesized by the precipitation polymerization of styrene in low toxic ethanol/water mixed solvent using K2S2O8/NaHSO3 as initiators at 25 degrees C. This work aimed at providing a new method of low-temperature preparation of monodispersed PS microspheres without cross-linker. Several reaction conditions, including reaction times, weight contents of initiators, and volume ratios of ethanol and water, were investigated in order to determine the effects of polymerization process on PS microspheres. The monomer conversion, and the size and yield of PS microspheres increased with reaction time and kept constantly after 12 h. With the increase of initiator content, the monomer conversion, and the size and yield of PS microspheres were increased, but the size distribution was nonuniform. When the weight contents of initiators K2S2O8 and NaHSO3 relative to that of styrene, were no more than 2. 0% and 1. 3%, respectively, PS microspheres were monodispersed. When the volume content of water in ethanol/water mixed solvent changed from 10% to 40%, the monomer conversion, and the yield of PS microspheres were increased, and monodispersed PS microspheres can be obtained. However, when the volume content of water was more than 40%,these performances would be decreased with wide microsphere distribution. When the stirring speed was changed from 600 r/min to 1200 r/min, PS microspheres had a little difference in size, yield and monomer conversion. The formation mechanism of PS microspheres was studied.
