Summary:Method for producing polyoxyalkylene glycols or polyoxyalkylene glycol copolymers from polyoxyalkylene glycol formates or from the formic esters of polyoxyalkylene glycol copolymers by reacting the formic esters of polyoxyalkylene glycols or of polyoxyalkylene glycol copolymers in liquid phase in the presence of a heterogeneous catalyst containing as the catalytically active component rhenium and/or at least one element of subgroup VIII of the periodic table.
