摘要: A novel polyhedral oligomeric octa(propargylaminophenyl)silsesquioxane (OPAPS, (SiO1.5C6H4NHCH2CCH)8) was prepared from octa(aminophenyl)silsesquioxane and propargyl bromide. The chemical structure of OPAPS characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance, X-ray diffraction (XRD), high-performance liquid chromatography, gel permeation differential scanning calorimetry, thermal gravimetric analysis (TGA). the thermally cured polymer FTIR, XRD, TGA. It had good stability. TGA demonstrated that decomposition temperatures (Td5) in nitrogen air were 455.6 458.8°C, respectively. curing reaction kinetics studied some kinetic parameters obtained. © 2012 Wiley Periodicals, Inc.
