Abstract: The invention relates to a method for producing polytetrahydrofuran and polytetrahydrofuran copolymers, diesters or monoesters thereof by polymerising tetrahydrofuran in the presence of at least one telogen and/or comonomer on acid- activated montmorillonite catalysts, whereby the ratio of the montmorillonite structure to the sum of the muscovite and kaolin structure in the montmorillonite catalyst, which is determined from the intensities of the reflexes measured at 5.5~ 2È for montmorillonite, 9.0~ 2È for muscovite and 12,5~ 2È for kaolin is, after acid activation, at least 5:1.
