Polyetherpolyols useful for the production of polyurethanes, are prepared by base catalyzed reaction of H-functional initiators prepared by reaction of dialkanolamines and diisocyanates

摘要

Polyetherpolyols (I) are prepared by base catalyzed reaction of H-functional initiator substances with alkylene oxides whereby the H-functional initiator substances are dialkanolamines and diisocyanates and optionally other co-initiators.
