Process for the preparation of polyether polyols with reduced unsaturation |
| abstract |
Polyether polyols having an equivalent weight of from 200 to 4000 are prepared by the process of this invention. The process uses barium- or strontium-containing alkoxylation catalysts to provide products with reduced unsaturation in comparison to similar products produced with potassium hydroxide catalysis. In a preferred embodiment of the process, water is added during the reaction of the monoepoxy compound with the initiator. The quantity of water added is one percent or less by weight of the total weight of monoepoxy compound to be reacted with the initiator. |
