Hydrolysierbare und polymerisierbare Silane, Verfahren zu deren Herstellung sowie deren Verwendung

The invention relates to hydrolizable and polymerizable silanes, processed for their production and their application for the production of silicic acid (hetero) polycondensates and (hetero) polymers. The silanes according to the invention have the general formula of formula 1, in which the residue and indices have the following meaning: A = 0, S, NH or C(O)O; B = a straight-chain or branched organic residue with at least one C = C double bond and 4 to 50 carbon atoms
