Abstract

We have studied by ²⁹Si NMR and small angle neutron scattering the cross-linking by formation of siloxane bridges of two amino-epoxy-silane molecules at different concentration in acidic water. We relate our observations to the fact that one of the studied systems never gels, while the second one displays a concentration threshold for gelation that is accounted for by percolation theory.
