摘　　要：以丙酮为溶剂,采用不同引发剂BF3、H2SO4、KOH引发氧化苯乙烯聚合。结果表明,3种引发剂的聚氧化苯乙烯产率均较高,其中BF3作引发剂聚合条件要求最低,所得聚合产物的颜色略浅、粘度较大;丙酮用量增加,聚氧化苯乙烯产率降低、颜色变浅、粘度变小。NMR表征聚合产物结构具有多分散性。With acetone as solvent,styrene oxide（SO） had been polymerized initiated by different metal-free initiator BF3,H2SO4 and KOH.The results showed that all the yields of poly（styrene oxide） were relatively high.The polymerization condition was the midest when BF3 was used as initiator,for which the polymer had relatively lighter color and higher viscosity.When the addition amount of acetone increased,the poly（styrene oxide） decreased in yield,color and viscosity.NMR Analysis showed that structure of the polymer had polydispersity.
