Hybrid materials derived from modified styrene-butadiene-styrene copolymer(SBS) and silica through the sol-gel process

Non-bonded and covalently bonded organic-inorganic hybrids materials, SBS-N O2/SiO2, SBS-NH2/SiO2 and SBS-Si(OCH3)(3)/SiO2. were prepared by the sol-ge l process using tetraethoxysilane (TEOS) in presence of modified SBS, SBS-N O2, SBS-NH2 and SBS-Si(OCH3)(3). respectively, with HCl as a catalyst. The modified SBS was prepared without damage its molecular weight and chemical structure, which was identified by the means of FTIR spectroscopy, elementa ry analysis, and Wijs titration. The interfacial force and the properties s uch as hemical resistance. elongation, thermal stability, and dynamic mecha nical properties of the hybrids were investigated in detail.
