Abstract: Preparation of reduction products of 4-hydroxybutyric acid derivatives of the general formula IIa in which one of the radicals A and B denotes a methylene group and the other a cyclopropylidene group, or of C1-C4-alkyl esters (IIb) or of lactones (IIc) of these acids IIa, by catalytically hydrogenating the compounds IIa or IIb or IIc with hydrogen in the presence of a heterogeneous hydrogenation catalyst, novel compounds prepared by this process and polymers prepared therefrom.
