Abstract
The present invention relates to a process for producing inorganic or organic-inorganic (hybrid) materials by hydrolysis and condensation of mono- or low molecular alkoxides and their use for coating surfaces and modifying organic polymers.
Claims10
Process for producing sol-gel compositions from cyclic carbosiloxanes and (organo-)metallic alkoxides with a solvent content less than 60 wt. % and a stability in storage of at least 7 days, characterised in that the process steps
- A) reacting a mixture containing cyclic carbosiloxanes and (organo-)-metallic alkoxides with water in the presence of a catalyst and optionally additional solvent, and
- B) partial or complete removal of the alcohols liberated during hydrolysis and condensation and of the optionally added solvents
- are carried out in succession.
