由于三氟乙烯基芳基醚单体独特的聚合机理和反应温度, 因此难以通过顺序投料法来合成含有全氟环丁基芳基醚结构的嵌段共聚物. 我们通过端基修饰的方法在全氟环丁基芳基醚聚合物链端引入叠氮基团, 通过点击化学与含有炔基的聚乙二醇相连, 制备了含有全氟环丁基芳基醚的ABA三嵌段共聚物.

关键词: 嵌段共聚物, 端基偶联法, 点击化学, 全氟环丁基芳基醚聚合物

Because of the unusual polymerization mechanism and normal high polymerization temperature of trifluorovinyl aryl ether monomers, it is difficult to synthesize perfluorocyclobutyl aryl ether (PFCB)-containing block copolymer via sequential addition of monomers. Here a coupling reaction via click chemistry to prepare PFCB-containing ABA triblock copolymer is reported. An azide-ended PFCB polymer, which was firstly prepared by end-modification of methyl-ended PFCB polymer, was coupled with alkynyl-ended polyethylene glycol via the azide alkyne Huisgen cycloaddition.

Key words: block copolymer, end-functionalized group coupling method, click chemistry, perfluorocyclobutyl aryl ether (PFCB)
