Verfahren zur Lösemittelstabilisierung von Membranen

A solvent-stabilized membrane based on an original membrane (OM) (as a finished membrane or formed by phase inversion of a membrane-forming polymer based on (co)monomers with CH-acid group(s)) are obtained by crosslinking the OM in a crosslinker solution at pH 8-14 and from 35 deg C up to the boilin...

Beschreibung
Zusammenfassung:	A solvent-stabilized membrane based on an original membrane (OM) (as a finished membrane or formed by phase inversion of a membrane-forming polymer based on (co)monomers with CH-acid group(s)) are obtained by crosslinking the OM in a crosslinker solution at pH 8-14 and from 35 deg C up to the boiling point of the solvent in the solution, and then drying. An Independent claim is also included for the process as described above for the production of solvent-stable membranes.
