摘　　要：通过萘钠引发剂引发苯乙烯合成聚苯乙烯双阴离子,然后通过碘的氧化扩链合成含头头结构聚苯乙烯,并通过红外光谱、核磁共振氢谱对头头结构进行了表征.The article introduces the preparation and identification of HHPS. At first, dicarbanion salt was formed with NaN as inifer reagent, then, this dicarbonion salt was coupled by I_2 to form HHPS. The structure of HHPS was identified by IR,~1H NMR. The structure character was reflected both in IR and ()~1H NMR.
