摘　　要：采用原位插层法制备了苯乙烯-马来酸酐共聚物/蒙脱土(SMA/MMT)纳米复合材料,采用X射线衍射研究了苯乙烯与马来酸酐的配比、蒙脱土用量、引发剂浓度、溶剂类型、聚合温度等因素对插层效果的影响。结果表明,当MMT的用量为3%(质量分数,下同)时,可制得剥离型的SMA/MMT纳米复合材料;当苯乙烯与马来酸酐的质量比为1:1,MMT用量为15%、引发剂用量为1%、以丁酮为溶剂、聚合温度为90℃时,可制备出部分剥离型的SMA/MMT纳米复合材料。In-situ intercalation was used to prepare poly （styrene-co-maleic anhydride）/ montmorillonite （SMA/MMT） nanocomposites. The effects of the ratio of styrene and maleic anhydride, the content of MMT and initiator,the kinds of solvent and polymeric temperature on the layer spacing of nanocomposite were studied by XRD. The results show that when the content of the montmorillonite is 3% （mass fraction）,the montmorillonite in SMA/ MMT nanocomposites is exfoliated. When the ratio of styrene and maleic anhydride is 1 ： 1, montmorillonite content is 15%, the initiator is 1%0, butanone as solvent, polymerization temperature is 90℃, the montmorillonite in SMA/MMT nanocomposites is partly exfoliated.
