摘　　要：将聚(苯乙烯-丙烯酰胺)季铵盐(PSAM)修饰蒙脱土(MMT)与尼龙(PA)6熔融共混,制备了PA6/PSAM/MMT纳米复合材料。考察了在MMT含量相同的情况下不同丙烯酰胺含量的PSAM修饰MMT对纳米复合材料力学性能的影响,并通过热重分析、X射线衍射等方法对此种纳米复合材料进行了表征。结果表明,当PSAM中丙烯酰胺的质量分数为10%时,PA6/PSAM/MMT纳米复合材料的综合性能较好。PA6/PSAM/MMT nanocomposites were prepared by melt blending ot poly（styrene-co-acrylamide） quaternary ammonium salts modified clays with nylon 6. The mechanical properties of PA6/PSAM/MMT nanocomposites prepared fi＇om MMT modified by PSAM with different contents of acrylamide units were studied. Nylon 6 and its composites were characterized by thermo gravimetric analysis and X ray diffraction. The results showed that the comprehensive properties were good when the content of acrylanfide units in PSAM was 10%.
