Hyperbranched polymers have received remarkably interest as a simpler-synthesized-substitution material of dendrimers. Herein, we describe the utilization of a flow reactor for synthesis of hyperbranched by photoinduced reversible addition–fragmentation chain-transfer(RAFT) self-condensing vinyl polymerization in methanol/water solution. By using Eosin Y as photocatalyst, hyperbranched polymers were synthesized under LED light, presence of oxygen and room temperature. Compared to the batch polymerization, flow polymerization demonstrated significantly higher conversion and narrower distribution. Molecular weight, branching length and branching density were able to be controlled by adjusting the predetermined feeding ratio of Monomer: Chain transfer agent: Inimer. The strategy developed here enables the preparation of hyperbranched polymers by a simple procedure, under extremely mild and aqueous condition.
