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