A new method has been developed for the synthesis of hyperbranched (arborescent) polymers. This synthetic strategy utilizes the self-grafting of active (living) polystyrene chains under quasiliving polymerization conditions. High yields of grafting can be achieved in a convenient one-pot reaction after the monomer consumed in the polymerization process. Measurements by GPC equipped with viscosity detector and proton NMR indicate the validity of the proposed intermolecular alkylation mechanism leading to highly branched polymers with low viscosity.
