  • Method for the preparation of polyoxyalkylene polyols
    Patent number: 10961346
    Abstract: The invention relates to a two-stage method for the preparation of polyoxyalkylene polyols having low equivalent molar masses, in which the method requires no reprocessing. The invention is characterized in that, in the first stage, a polyoxyalkylene polyol precursor is provided, which contains the salts of a strong Bronsted acid, and in that, in a second stage, the polyoxyalkylene polyol precursor is further reacted with alkylene oxides under DMC catalysis.
