Molecular weight polyether polyol with weak odor, process for its production, and its use in the production of polymers, cosmetics and pharmaceuticals synthesized from polyether polyols

摘要

The high molecular weight polyether polyol having a weak odor is prepared by purifying a polyether polyol at a temperature of 110 to 150 ° C and a pressure of 10 to 70 hPa while adding 5 to 30% by weight of water, wherein the water is added under a metered amount of 1 to 5 hours Lt; / RTI through the polyether polyol to be purified over time.
