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)
