Looped flow RAFT polymerization for multiblock copolymer synthesis

Abstract

A looped flow process was designed for the synthesis of well-defined multiblock copolymers using reversible addition–fragmentation chain transfer (RAFT) polymerization. The reaction conditions were optimized to reach high conversions whilst maintaining a high end-group fidelity. The loop set-up proved to be a flexible, robust and time-efficient process for scaling-up multiblock copolymers.
