| 摘要 |
The present invention relates to a process for cross-linking a silane with the structure (IIa) for the preparation of a product, comprising component (III) twice, in triplicate or in a higher quantity, where the radicals B, R1, Ra, R′, X1 and the indices a and b are defined as above for structure (IIa) and can be identical or different in each case, or for the cross-linking of a condensate, a partial condensate, a polymer or a partial polymer comprising structural units with the structure (IIb) via the bond R1—, characterized in that a silane with the structure (IIa), or an isomer, a re-esterification product or a condensation product of said silane, which condensation product was formed by loss of an alcohol molecule, or a condensate, a partial condensate, a polymer, or a partial polymer comprising structural units of structure (IIb) is reacted with a compound having the structure (IV) Q-R5[-Q′]c,  (IV). |
