Improvements relating to polyurethanes |
| abstract |
A process for preparing a flexible polyurethane foam, the process comprising reacting a polyether polyol with foam-forming reactants to provide the polyurethane foam, wherein the polyether polyol comprises at least 50ppm of latent normal aldehyde content, and/or the polyether polyol is obtainable from the ring-opening polymerization of alkylene oxide comprising at least 200ppm of free aldehyde content. Also disclosed are foams obtainable by said process and the use of polyether polyols. |
