| abstract |
A process for the production of silicic acid heteropolycondensates, wherein at least one hydrolysable silicic acid derivative; at least one substituted silane; optionally at least one functional silane and/or optionally at least one substantially involatile oxide soluble in the reaction medium or at least one compound forming a substantially involatile oxide are condensed in the presence of at least the quantity of water stoichiometrically required for hydrolysis and optionally in the presence of a condensation catalyst and/or a solvent. The polycondensates are useful in the production of membranes and adsorbents. |
