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.

L'invention concerne un polyol de polyéther co-initié produit par suspension d'un composé polyhydroxylé solide dans un polyol initié avec de l'amine, par chauffage de ladite suspension et alcoxylation de la suspension portée à chaud. Ces polyols de polyéther co-initiés sont particulièrement utiles dans la production de polyuréthannes.
