摘　　要：研究了以大孔型氯甲基化交联聚苯乙烯母球为原料,与烷基氨基醇钠反应,合成带有醚键结构的叔胺树脂,进一步季铵化为强碱性阴离子交换树脂。系统研究了叔胺化工艺条件,并对季铵树脂进行了热稳定性评价。结果表明,与常规的强碱性阴离子交换树脂相比,其热稳定性已有明显提高,使用温度可以提高20℃左右,拓展了强碱性阴离子交换树脂的应用领域。In the paper, a strong basic anion exchange resin with ether structure, which was synthesized from macroporous chloromethylized crosslink polystyrenemer and sodium alkylaminoalkoxide, and then quaternary ammonized, was researched. The reaction conditions in tertiary ammonization were also observed. The thermal stable test of quaternary ammonized resin shows that, compared with normal strong basic anion exchange resin, the thermal stability of this kind anion exchange resin is enhanced obviously, and its working temperature can be about 20℃ higher, and its using scope can be expanded.
