    Abstract: A process for the preparation of polytetrahydrofuran or C2- to C10-alkylene oxide-tetrahydrofuran copolymers having a mean molecular weight of from 250 to 20000 daltons by cationic polymerisation of tetrahydrofuran or tetrahydrofuran and C2- to C10-alkylene oxides in the presence of a promoter, in which process the catalyst used is a mixture of one or more C2- to C6-di- or tricarboxylic acids with boric acid.
