Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Polyurethanschaumstoffen durch Reaktion einer Isocyanat-Komponente mit einer gegenüber Isocyanaten reaktiven Komponente, die mindestens ein Polyethercarbonatpolyol umfasst, und wobei die Umsetzung in Gegenwart von Harnstoff oder dessen Derivaten erfolgt. Die Erfindung betrifft weiterhin durch das erfindungsgemäße Verfahren hergestellte Polyurethanschaumstoffe und deren Verwendung.
(EN)
The invention relates to a method for producing polyurethane foams by reacting an isocyanate component with a component that is reactive to isocyanates and that comprises at least one polyether carbonate polyol, the reaction taking place in the presence of urea or derivatives thereof. The invention also relates to polyurethane foams produced by the claimed method and to the use thereof.
(FR)
La présente invention concerne un procédé de production de mousses de polyuréthane par mise en réaction d'un composé isocyanate avec un composé réactif aux isocyanates renfermant au moins un polyéthercarbonate polyol, cette réaction étant réalisée en présence d'urée ou de ses dérivés. L'invention concerne également des mousses de polyuréthane produites selon ledit procédé ainsi que leur utilisation.
