Synthesis, Characterization and Study Thermal Stability of New Polythiadizole Derivatives / Silica Nanocomposites

Abstract

New nanocomposites containing polythiadizole were synthesized by free radical polymerization and examined their thermal properties. All monomers, polymers and nanocomposites were characterized by FT-IR spectroscopy. The thermal stability were investigated by thermo gravimetric (TG), differential scanning calorimetry (DSC) and differential thermal analysis (DTA). Synthesis of polymer and their nanocomposite had characterization by FT-IR, thermogravimetry (TG), Diffraction scanning callomatry DSC, Differential Thermal analysis DTA,the state of the nanocomposite were evaluated via X-ray diffraction (XRD).The results of thermal analysis showed that nanocomposite more stable than their polymers.
