| description | A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst which is a multimetal oxide compound. A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst, i.e. a multimetal oxide compound of formula (I). M1p(M2qOn(OH)2(3-n))x (I) M1 = at least 1 element from the groups IA, IIA, IIIA, IVA, VA, IB, IIB, IIIB, IVB, VB, VIB, VIIB and/or VIIIB; M2 = at least one element from groups IVA, VA and/or VIA, n = 2 or 3, p = 0 or fractional or whole number greater than 0, q = fractional or whole number greater than 0, x = 1-20 fractional or whole number. An Independent claim is included for a polyetherol obtained as above. |
