Composite membrane has pre-crosslinked PVA separation layer for separation of water from mixtures with organic compounds at up to specified temperature, obtained by post-crosslinking without addition of acids

Composite membrane has pre-crosslinked PVA separation layer for separation of water from mixtures with organic compounds at up to specified temperature, obtained by post-crosslinking without addition of acids

A composite membrane with at least one separation layer of pre-crosslinked polyvinyl alcohol is subjected in a separate process to post-crosslinking at an elevated temperature without the addition of acids or compounds splitting off acids. Die Erfindung betrifft eine Kompositmembran mit wenigstens e...

description A composite membrane with at least one separation layer of pre-crosslinked polyvinyl alcohol is subjected in a separate process to post-crosslinking at an elevated temperature without the addition of acids or compounds splitting off acids. Die Erfindung betrifft eine Kompositmembran mit wenigstens einer Trennschicht aus vorvernetztem Polyvinylalkohol. Sie kennzeichnet sich dadurch aus, dass die Membran in einem separaten Verfahrensschritt einer Nachvernetzung bei erhöhter Temperatur und ohne Zusatz von Säure oder Säure spaltenden Verbindungen unterworfen wird.
