Co-initiated polyols useful for the production of rigid polyurethane foams |
| 摘要 |
A co-initiated polyether polyol is produced by suspending a solid polyhydroxyl compound in an amine-initiated polyol, heating the suspension and alkoxylating the heated suspension. These co-initiated polyether polyols are particularly useful for the production of polyurethanes.
