Abstract: Polytetrahydrofuran, tetrahydrofuran copolymers, diesters or monoesters of these polymers are prepared by polymerizing tetrahydrofuran in the presence of at least one telogen and/or comonomer on a heterogeneous carrier catalyst which contains on an oxidic carrier material as active mass a catalytically active amount of at least one oxygenous molybdenum and/or tungsten compound and, when the precursor compounds of the active mass have been applied to the carrier material precursor, has been calcined at temperatures of between 500° C. and 1000° C. The catalyst used contains a promotor which comprises at least one element or a compound of an element of the 2nd, 3rd including the lanthanides, 5th, 6th, 7th, 8th or 14th group of the periodic system of elements.

Abstract: The present invention relates to a process for the alkoxylation of organic compounds comprising the reaction of at least one organic compound with at least onealkoxylating agent in the presence of a catalyst system, wherein a polyetheralcohol is obtained. The catalyst system comprises a metallo organi c framework mate-rial comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to sa id metal ion. Furthermore it relates to polyurethanes or polyurethane foams, which are obtainable by using a prepared polyether alcohol as a starting material.
