摘要：We have successfully synthesised diglycidylether bisphenol-A (DGEBA)/hydroxyl-terminated polydimethylsiloxane (HTPDMS) grafting copolymer through condensation of hydroxyl groups. Diethylenetriamine (DETA) was used as a curing agent to crosslink DGEBA and DGEBA-HTPDMS. The chemical structure of the DGEBA-HTPDMS grafting copolymer was confirmed by Fourier Transform Infra-Red (FT-IR) spectroscopy. The introduction of HTPDMS in the DGEBA system slightly increase resilience properties and reduced hardness Shore-D. No phase separation was observed by Scanning Electron Microscopy (SEM). Thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) showed that the thermal stability of the DGEBA system improved. While the presence of HTPDMS shows more stability towards the solvent. These results showed Si-O-Si segments can enhance the properties of the existing DGEBA.
