ABSTRACT:
A process for the production of silicic acid heteropolycondensates wherein at least one substituted silane; at least one functional silane; at least one hydrolysable silicic acid derivative and optionally at least one substantially involatile oxide soluble in the reaction medium, or a compound convertible thereto, 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 heteropolycondensates prepared by this process are useful in the preparation of coatings for substrates, which coated substrates are useful as supports in the culture of living cells.
