Abstract: A method is disclosed of producing polytetrahydrofurane or polytetrahydrofurane monoesters of C1-C10 monocarboxylic acids by polymerisation of tetrahydrofurane on a heterogenous catalyst in the presence of one of the following telogens: water, 1.4-butane diol, polytetrahydrofurane with a molecular weight of 200-700 Da, a C1-C10 monocarboxylic acid, or mixtures of these telogens. The catalyst used is a carrier catalyst which contains a catalytically active quantity of an oxygen-containing tungsten or molybdenum compound or mixtures of such compounds on an oxide carrier material and has undergone calcination at temperatures of 500-1000 ~C after the precursors of the oxygen-containing molybdenum and/or tungsten compounds have been deposited on the carrier material precursor.
