利用磺酰胺基团作为新的活化基团,制备了聚(芳基醚磺酰胺),用于核型芳族取代聚合。通过2,4-二氟苯磺酰氯与二甲胺之间的简单取代反应,可以高收率合成活化的单体2,4-二氟-N,N-二甲基苯磺酰胺。该单体在亲核芳族取代机理中的反应性是通过在PM3浓度下的半经验计算以及1 H,13 C和19 F NMR光谱估算的。数据支持磺酰胺具有足够的吸电子能力,以活化芳基氟化物以被苯氧化物亲核试剂取代。用叔建模反应-丁基苯酚证实2,4-二氟-N,N-二甲基苯磺酰胺的芳基氟化物可以定量产率置换,表明该方法适用于形成聚合物。使用双酚A,4,4'-双酚,双酚AF和对苯二酚作为共聚单体,生产了多种新型聚合物。通过凝胶渗透色谱,溶液粘度测定,NMR光谱,热重分析和差示扫描量热法对聚合物进行表征。高分子量聚(芳基醚磺酰胺)具有163至199°C的中度至高玻璃化转变温度。表现出该聚合物是热稳定的,在氮气气氛中从398到442°C发生了5%的重量损失。
