Inside Cover: Chain‐Growth Click Polymerization of AB 2 Monomers for the Formation of Hyperbranched Polymers with Low Polydispersities in a One‐Pot Process (Angew. Chem. Int. Ed. 26/2015)

The chain‐growth polymerization of AB 2 monomers in a one‐pot process enables the synthesis of hyperbranched polymers with high molecular weight, low polydispersity, and a high degree of branching. In their Communication on page 7631 ff., H. Gao et al. show that during the copper‐catalyzed azide–alkyne cycloaddition polymerization of the AB 2 monomers, all Cu catalysts are bound to polytriazole polymers at low conversion, which results in a chain‐growth mechanism favoring polymer–monomer reactions.
