Abstract

Graphical abstract: Highlights: Cationic polymerization in a flow microreactor system gave multifunctional polymers. A dendritic cation having bromide moieties was used as the initiator. A silyl enol ether having bromide or alkynyl moieties was used as the terminators. Coupling reactions of both polymer ends gave linear-dendritic hybrid polymers. Abstract: Cationic polymerization of vinyl ethers using a multifunctional dendritic initiator and multifunctional terminators in a flow microreactor system gave polymers having multiple functionalities on both ends. Subsequent transformation of the resulting polymers through Suzuki-Miyaura coupling and/or copper-mediated azide-alkyne cycloaddition gave linear-dendritic hybrid polymers.
