摘　　要：以n-BuLi/THF为引发体系采用阴离子聚合合成不同分子量的聚苯乙烯基锂,再与过量对二氯苄合成聚苯乙烯基苄氯,通过聚苯乙烯基苄氯与三甲胺反应制备季铵盐,用离子交换法合成不同分子量的聚苯乙烯季铵盐修饰蒙脱土。通过1HNMR、TGA、XRD等测试手段对以上聚苯乙烯类化合物及修饰蒙脱土的结构进行了表征。Oligomeric polystyrylmethyl benzyl chlorides with different molecular weight were prepared from styrene by anionic polymerization using n-BuLi/THF as initiator and α,α′-Dichloro-p-xylene as the terminating reagent. The polystyryl ammonium salt was obtained from the reaction of trimethyl amine with the corresponding benzyl chloride, and then the polystyryl modified clays were prepared through cationic exchange of the sodium ion in the clay with the corresponding polystyryl ammonium salt. The polystyryl chemicals were characterized by ^1H NMR, and its modified clays were characterized using XRD and TGA.
