[图]通过聚（4-乙烯基苄基氯-共二乙烯基苯）PolyHIPE 材料中氯的亲核置换制备整体聚合物载体和清除剂。整体式 PolyHIPE 与三（2-氨基乙基）胺、4-氨基丁醇、三（羟甲基）氨基甲烷、吗啉和六亚甲基四胺发生反应，生成具有高转化率的具有氨基和羟基官能团的官能化聚合物。在环境温度下，单片聚(4-乙烯基苄基氯-共-二乙烯基苯)PolyHIPE的三(2-氨基乙基)胺衍生物可以有效、快速地从溶液中清除4-氯苯甲酰氯。
[GRAPHIC]Monolithic polymer supports and scavengers were prepared via nucleophilic displacement of chlorine in poly(4-vinylbenzyl chloride-codivinylbenzene) PolyHIPE materials. Reactions of monolithic PolyHIPE with tris(2-aminoethyl)amine, 4-aminobutanol, tris(hydroxymethyl)aminomethane, morpholine, and hexamethylenetetramine led to functionalized polymers with amino and hydroxy functionalities with high degrees of conversion. 4-Chlorobenzoyl chloride was efficiently and rapidly scavenged from solution by the tris(2-aminoethyl)amine derivative of monolithic poly(4-vinylbenzyl chloride-co-divinylbenzene) PolyHIPE at ambient temperature.
