摘要：
Abstract of the Disclosure: Products of the reduction of 4-hydroxybutyric acid derivatives of the formula IIa ##STR1## where one of A and B is methylene and the other is cyclopropylidene, or of C.sub.1 --C.sub.4 --alkyl esters (IIb) or lactones (IIc) of these acids IIa, are prepared by hydrogenating the compounds IIa or IIb or IIc catalytically using hydrogen in the presence of a heterogeneous hydrogenation catalyst, giving novel compounds which can be used to prepare polymers.
