[reaction: see text] Monolithic polymer supports and scavengers were prepared via nucleophilic displacement of chlorine in poly(4-vinylbenzyl chloride-co-divinylbenzene) 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.
[反应:见正文] 通过聚(4-乙烯基苄基氯-共-二乙烯基苯)聚高内相乳液材料中氯的亲核取代反应制备了整体聚合物载体和清除剂。整体聚高内相乳液与三(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的反应生成了具有高转化率的含氨基和羟基官能团的功能化聚合物。在室温下,整体聚(4-乙烯基苄基氯-共-二乙烯基苯)聚高内相乳液的三(2-氨基乙基)胺衍生物能有效且快速地从溶液中清除4-氯苯甲酰氯。
