Mo-2615 LeA 22,766 A HOMOGENEOUS STORAGE STABLE SALT-CONTAINING MIXTURE ABSTRACT OF THE DISCLOSURE Homogeneous storable mixtures containing small quantities of salts and having a high mixed hydroxyl number or mixed hydroxyl/amine number are made by mixing (a) a polyoxyalkylene polyol and/or polyolamine and/or polyamine based on an alkyloxirane having a molecular weight of from 400 to 12,000, (b) a low molecular weight polyol which is not completely miscible with (a) and a solution-promoting additive in quantities such that for every 100 parts of (a), from 1 to 200 parts of (b) and from 0.01 to 10 parts of (c) are present. The solution-promoting additives are salts of cations of Groups IA, IIA and IIIA of the Periodic System of Elements or ammonium or mono- to tetra-alkylammonium ions and anions formed by removing at least one proton from an acid having a Ks-value of at least 10-7. These mixtures are particularly useful in the production of polyurethanes. Mo-2615 LeA 22,766
