Abstract
In this study interpenetrating polymer networks (IPNs) based on bisphenol A diglycidyl dimethacrylate (BisGMA) and diglycidyl ether of bisphenol A (DGEBA) with or without native fumed silica nanoparticles were prepared by in situ polymerization. The properties of the IPNs and hybrid IPNs were evaluated using different thermal techniques as differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and thermogravimetrical analysis (TGA). The mechanical properties were also determined. Keywords: dimethacrylate, epoxy resin, interpenetrating polymer network, fumed silica
