    Dendritic Hyperbranched Polymers as Tougheners for Epoxy Resins

      Graphical Abstract
      • Abstract
    • Hyperbranched poly(amine-ester)(HBP) was synthesized via one-step procedure.Viscosity of HBP was tested.Dendritic hyperbranched polymers(HBP) as tougheners in epoxy resins was prepared for polymer.The impact strength and bending properties were studied.Impact fracture morphology was observed with SEM.As a result,the viscosity of HBP decreased with the increasing temperature.The impact strength is increased from 9.8 kJ/m~2 to 22.4 kJ/m~2.HBP has effect on bending strength and modulus.Impact fracture morphology behave toughness feature.
