Method for the production of polyetherols

Preparing polyetherol, comprises carrying out catalytic ring-opening polymerization of alkylene oxide with at least one at least monofunctional compound that is reactive with alkylene oxide, using at least one N-heterocyclic carbene catalyst. An independent claim is also included for the polyetherol...

Beschreibung
Zusammenfassung:	Preparing polyetherol, comprises carrying out catalytic ring-opening polymerization of alkylene oxide with at least one at least monofunctional compound that is reactive with alkylene oxide, using at least one N-heterocyclic carbene catalyst. An independent claim is also included for the polyetherol producible by the above method. Die vorliegende Erfindung betrifft Verfahren zur Herstellung von Polyetherolen, insbesondere Polyetherol-Blockstrukturen, neue Katalysatoren zum Einsatz in diesen Verfahren, und die durch das erfindungsgemäße Verfahren herstellbaren Polyetherole. Weiterhin betrifft die vorliegende Erfindung die Verwendung der erfindungsgemäß herstellbaren Polyetherole zur Herstellung von Polyurethanen.
