Abstract
A polyalkylene ether glycol composition containing a nitrogen-containing compound. The nitrogen-containing compound constitutes 0.2 to 40 mass ppm of the polyalkylene ether glycol in terms of nitrogen atoms, and the nitrogen-containing compound has a boiling point in a range of −40° C. to 120° C. at atmospheric pressure. An elastic stretchable fiber, a polyurethane, a synthetic leather, or a thermoplastic elastomer containing the polyalkylene ether glycol composition.
