A controlled/”living” click polymerization method developed by researchers at the Institute of Science Tokyo and Nagoya University enables precise chain-growth of AB-type monomers—traditionally limited to step-growth processes—by leveraging copper-catalyzed azide–alkyne cycloaddition. The approach achieves well-defined polymers with narrow dispersity and enables the bidirectional synthesis of ABA-type block copolymers, offering a powerful new strategy for constructing functional macromolecular architectures from a wide range of monomers.
