摘　　要：通过共聚交联方法将长链碳烯-苯乙烯包覆到锆胶表面上,得到聚合物包覆固定相,再对该填料进行磺化引入离子官能团到聚合物表面,得到混合型固定相.用扫描电镜和红外光谱对这些填料进行了表征,考察了混合型固定相的毛细管电色谱性能,并用该填料分离了苯甲酸和苯胺等化合物.Novel sulfonic acid and carbon chains of mixed-mode packing materials were synthesized through sulfonating polymer-encapsulated zirconia covered by a porous copolymer of olefinic hydrocarbon and divinylbenzene on its surface. This new packing material was evaluated in CEC, physical properties of these stationary phases were determined with SEM and IR. Chromatographic characteristics were evaluated in CEC.
