ABSTRACT:
In an improved process for the preparation of polyether compositions, amine-initiated, alkaline catalyzed polyethers are neutralized with a substantial excess of formic acid that neutralizes the 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.
