Abstract

17O NMR in solution using enriched water as reactant has been used to investigate cohydrolysis of dimethyldiethoxysilane and tetraethoxysilane, as well as methyltriethoxysilane and tetraethoxysilane. Co-condensation reactions were clearly identified in both systems : the amount of oxo bridges between the two kinds of Si units is rather large, and those bridges are stable during aging, which favor a good chemical homogeneity in the final gels. This last point was investigated on the related dried gels by 29Si Magic Angle Spinning NMR, using Cross-Polarization (CP) technique that allows to probe the local environment of the various Si sites through 29Si-1H dipolar interactions.
