摘要: Polyureas having different heterocyclic groups were reacted, respectively, with commercial epoxy resins, i.e., diglicidyle ether of bisphenol A and brominated DGEBA. The resultant polyurea–epoxy systems designated as I(a–f) II(a–f), respectively. All the characterized by FTIR spectral studies, thermogravimetric analysis number average molecular weight, estimated non-aqueous conductometric titration. then mixed appropriate amounts DGEBA resin, monitored for differential scanning calorimetry, and, based on this, glass fiber-reinforced composites prepared. laminates physical mechanical properties.
