| titleOfInvention | Method for producing long-chain polyether polyol without post-treatment |
| abstract | (57) [Summary]nThe present invention relates to a method for producing a long-chain polyether polyol without post-treatment. First, oligomeric alkoxylation starting compounds having a molecular weight of 200 to 1000 are catalyzed by perfluoroalkylsulfonates of Group IIIA metals of the Periodic Table (according to the IUPAC nomenclature of 1970) at reaction temperatures of 80 to 200 ° C. , Obtained from low molecular weight starting materials by reaction with alkylene oxides at a catalyst concentration of 5-200 ppm. The starting compound is then reacted with an alkylene oxide to form a highly active DMC catalyst at a catalyst concentration of 30 ppm or less, based on the amount of polyether polyol produced, without work-up and catalyst separation. Produce high molecular weight long chain polyether polyols. |
