Modification of Epoxy Resins with Epoxide-Containing Acrylic Copolymers
Abstract:
A series of epoxide-containing acrylic polymer modifiers (HGMB) were synthesized. The dynamic mechanical behavior and impact strengths of the modified systems, epoxy resin E-51/4, 4'-diaminodiphenylmethane (DDM)/HGMB, were investigated. The results showed that both the structure and amount of the modifiers affected the impact strength and modulus of the modified systems significantly. The addition of 15%(mass fraction) HGMB (4.3% glycidyl methacrylate (GMA), 5 % hydroxyethyl methacrylate(HEMA), 25.7% methyl methacrylate (MMA) and 65 % butyl acrylate (BA) (mole fraction)) resulted in a 50% increase in impact strength and an obvious increase in Tg of the modified system but only little loss of its modulus.
