Synthesis of Hyperbranched Polystyrene and Its Fullerene End-capped Derivatives with Multifunctional Atom Transfer Radical Polymerization Initiator

Abstract

Abstract: A novel multifunctional ATRP initiator was synthesized by esterfication of a hyperbranched polyester Z5[from pentaerythritol and 2,2-bis(hydroxymethyl)propionic acid]. The macroinitiator contained approximately 19 initiating sites per molecule. It was used for the ATRP of styrene mediated by CuCl and N,N,N,N",N"-pentamethyldiethylenetriamine(PMDETA) in cyclohexanone at 100 ℃. The molar ratio of monomer to initiator was 100/1, 200/1, 300/1, respectively. Through hydrolysis of hyperbranched polymer, the arm chain length of the hyperbranched polystyrene was detected by GPC, the results showed that ATRP process under these conditions was well controlled. The hyperbranched PS was further reacted with sodium azide in dimethyl formamide at room temperature to yield an azide end-functional hyperbranched polymer. Then a covalently bonded C₆₀-hyperbranched polymeric derivative was achieved by reacting C₆₀ with the sodium azide end-capped hyperbranched polymer in 1,2-dichlobenzene solution at 130 ℃. In the hyperbranched polymeric derivatives, the mass fraction of the fullerene was about 1%—2.5%.
