Abstract
The invention relates to a method for producing polyurethane soft foam by reacting an isocyanate component with a component which is reactive towards isocyanates. The component which is reactive towards isocyanates comprises a mixture of at least one polyether carbonate polyol and a polyether polyol as the constituents. In the component which is reactive towards isocyanates, the total proportion of polyether carbonate polyols is =20 wt. % to =80 wt. % and the total proportion of polyether polyol is =20 wt. % to =80 wt. %, based on the total weight of the provided polyols. The invention further relates to a polyurethane soft foam produced using said method.
