Abstract: In the present invention there is disclosed a process for preparing copolymers of tetrahydrofuran and but-2-ine-1,4-diol, containing double bonds. The preparation process is characterized by subjecting the tetrahydrofuran and but-2-ine-1,4-diol copolymers to partial hydrogenation on a hydrogenation catalyst, whereby these tetrahydrofuran and but-2-ine-1,4-diol copolymers are prepared by catalytic polymerization of tetrahydrofuran on a heterogeneous acidic polymerization catalyst having acidity of acid centers pKia less than +2 in concentration of at least 0.005 mmol per gram of the catalyst, in the presence of but-2-ine-1,4-diol. For this preparation process a plurality of polymerization catalysts can be used. The catalyst preferably contains molybdenum or tungsten compound. It is further preferred that this catalyst is also doped with a sulfur or phosphorus compound.
