Abstract
A homogeneous, storage-stable, emulsifier-free polyol mixture having a high mixed OH-number and a high ethylene glycol content comprising 100 parts of a relatively high molecular weight polyalkylene oxide polyol having an OH-number of from 20 to 210, which contains at least 5%, and less than 80%, by weight, of terminal ethylene oxide blocks, from 0.1 to 30 parts of a low molecular weight diol mixture having an OH-number of 1200 to 1650 in the form of a reaction product of 1 mole of ethylene glycol with 0.1 to 0.5 moles of propylene oxide, optionally, up to 5 parts of di- and/or tri-functional compounds containing reactive hydrogen atoms and having a molecular weight of from 32 to 399, and optionally, other auxiliaries and additives known in the production of polyurethanes. Also, polyurethanes produced using these polyol mixtures.
