Abstract
The present application relates to a novel method of stabilizing the molecular weight of alkoxylates and stable compositions. The polyoxyalkylene compounds have incorporated into them, from the time of reaction of the alkylene oxide, a free radical type inhibitor which significantly improves stability of both the polymer.
