Abstract: A process for the batchwise preparation of polyoxybutylene polyoxyalkylene glycols by copolymerizing tetrahydrofuran with a 1,2-alkylene oxide in the presence of compounds containing reactive hydrogen, the polymerization being carried out over a bleaching earth catalyst or zeolite catalyst, and the 1,2-alkylene oxide being fed to the reaction mixture in such manner that the concentration of the 1,2-alkylene oxide in the reaction mixture is kept at below 2% by weight during the polymerization.
