Abstract
Process for preparing polyoxyalkylene ether diols, wherein the hydroxyl groups are substantially terminal hydroxyl groups, comprising mixing at least one polymerizable organic cyclic monomer, having a ring of 2 to 3 carbon atoms and an oxygen atom, and up to total of 18 carbon atoms, said oxide being chosen from the group consisting of epoxides, oxetanes, 3-substituted oxetanes and 3,3-disubstituted oxetanes, with water being present in an amount of about 0.0001 to 5% by weight, based on in the polymerizable oxide, in the presence of a catalyst in an amount of about 0.0001 to 15% by weight on said monomer, said catalyst comprising a double metal cyanide complex compound having the general formula Ma (Z) c. (H2O) ) d. (R) e, where Z is chosen from the group consisting of M '(CN) by M' [(CN) r (X) t] b where M is at least one metal selected from the group consisting of Zn (II), Fe (II), Fe (III), Co (II), Ni (II), Mo (IV), M or (VI), Al (III), V (IV), V (V), Sr (II), W (IV), W (VI), Mn (II) and Cr (III) M 'is a selected metal of the group consisting of Fe (II), Fe (II) Co (II), Co (III) Cr (ll), Cr (III), Mn (II), Mn (III), V (IV) and V ( V), X is an elected member of the group consisting of (see formula), R is an organic compound of low molecular weight that has up to 18 carbon atoms and is selected from the group consisting of alcohols, aldehydes, ketones, ethers, esters and amides, nitriles and sulfides, being a, b and c numbers whose values are a function of the valences and coordination indices of M and M ', with the total positive net charge of M, multiplied by a, essentially equal to the total negative net charge of Z multiplied by c, R is an integer, T is an integer, where R is greater than T, d is equal to 0 or an integer, and e is an integer; maintaining said mixture at a temperature at which said water and cyclic oxide will react to produce said polyoxyalkylene ether diols.
