Zusammenfassung:	In an improved process for the preparation of polyether compositions, amine-initiated polyethers are stabilized with a reducing agent. In a preferred embodiment the polyethers are simultaneously neutralized with a substantial excess of formic acid that neutralizes the alkaline catalyst and stabilizes the resultant composition. This is particularly advantageous where tertiary nitrogen is found in the amine initiator or in the polyether that results.
