Abstract
In a process for preparing a polyether alcohol d1) by reaction of a) at least one compound having at least three hydrogen atoms reactive with alkylene oxides and a molecular weight Mn of not more than 600 g/mol with b) an alkylene oxide by using c) a catalyst, said reaction is carried out in the presence of a polyether alcohol d) having a hydroxyl number of 100-800 mg KOH/g and a functionality of 1.5 to 8.
