A new synthesis approach for the preparation of highly branched anion exchange materials utilizing diamine and diepoxide reagents is described. Unlike previously reported condensation polymers prepared from primary amine and diepoxide reagents, anion exchange polymers prepared from diamines and diepoxide reagents exhibit exceptionally low affinity for polyvalent ions. Use of anion-exchange materials synthesized utilizing this new synthetic method for the analysis of common inorganic anions is demonstrated.

衍生自二胺和二环氧化物的静电连接的高度支化的阴离子交换相

描述了一种利用二胺和二环氧化合物制备高度支化阴离子交换材料的新合成方法。与先前报道的由伯胺和二环氧化物试剂制备的缩聚物不同，由二胺和二环氧化物试剂制备的阴离子交换聚合物对多价离子的亲和力极低。演示了使用这种新的合成方法合成的阴离子交换材料对常见无机阴离子的分析。
