A ternary hybrid of bismaleimide‐polyetherimide‐silica (BMI‐PEI‐SiO 2 ) was synthesized by sol‐gel reaction and characterized by scanning electron microscopy (SEM), energy dispersive X‐ray analysis (EDX), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicated that silica could be introduced into the blend of thermoplastic‐thermosetting system by sol‐gel reaction and dispersed uniformly as nanoparticles. The phase separation of BMI‐PEI was not affected apparently by the presence of silica. The coupling agent 3‐aminopropyl (triethoxy)silane was chosen to enhance the interaction between the polymer‐matrix and silica. Thermal properties and mechanical properties of the hybrids both were improved with increasing silica content. Copyright © 2005 John Wiley & Sons, Ltd.
