Polyalkylene ether glycol composition and method for producing polyurethane using the same

Abstract

A polyalkylene ether glycol composition including a polyalkylene ether glycol including an alkoxy group serving as a terminal group. The polyalkylene ether glycol composition has a hydroxyl value of 220 or more and 750 or less. The ratio of the number of alkoxy group terminals of the polyalkylene ether glycol included in the polyalkylene ether glycol composition to the number of hydroxyl group terminals of polyalkylene ether glycols included in the polyalkylene ether glycol composition is 0.00001 or more and 0.0040 or less. Provided is a polyalkylene ether glycol composition having excellent compatibility with low-molecular-weight polyols, having suitable reactivity when used as a raw material for polyurethanes, and capable of achieving intended physical properties.
