Composite membrane and process for its production
To produce a composite membrane, the solution of a polymer in a volatile organic solvent is spread on water, the solvent is allowed to evaporate, the polymer is crosslinked and the polymer film formed is transferred to a porous support membrane. The polymer is preferably a polysiloxane which is cros...

Summary: | To produce a composite membrane, the solution of a polymer in a volatile organic solvent is spread on water, the solvent is allowed to evaporate, the polymer is crosslinked and the polymer film formed is transferred to a porous support membrane. The polymer is preferably a polysiloxane which is cross-linked via polymer-bonded OH groups. The composite membrane is suitable, inter alia, for pervaporation. |
