Abstract
A series of solid sodium and potassium cyclotetrasiloxanolates was synthetized with high yields by hydrolytic condensation of 3-mercaptopropyltrimethoxysilane in the presence of potassium or sodium hydroxide. The obtained materials were characterized using solid state 29Si and 13C NMR, wide angle X-ray scattering (WAXS), elemental analysis, Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The influence of reaction conditions on the structure and physiochemical properties of the obtained products was studied.
