摘要：1. Process for the production of polyether polyols having an average molecularweight in the range of 200 to 10,000 and an average hydroxyl functionality of 2.0 to 7.0 bythe addition of one or more cyclic ethers, in the presence of an acid catalyst, to a starterconsisting of sugars and optionally polyhydric alcohols, characterised in that as startersA) formose which is optionally aldolated in the alpha -position, or B) liquid mixtures of a)high and/or low molecular weight polyhydroxyl compounds and/or mono- or di-saccharides and/or natural or synthetic invert sugars and b) formose which is optionallyaldolated in the alpha -position, are employed, those formoses being excluded whichhave been directly produced from formaldehyde-containing synthesis gases.
