The aim of this study was to estimate the structure of new polyurethanes with the potential to be used in medicine. Atactic poly[(R,S)-3-hydroxybutyrate], obtained via a ring-opening polymerization, and polycaprolactonediol or polyoxytetramethylenediol were used to built the soft segments. 4,4'-methylene dicyclohexyl diisocyanate and 1,4-butanediol were the components to form hard segments. Polyurethanes with low-molecular weight were obtained. The observation of FTIR and 1H-NMR spectra suggested that NH groups form two types of hydrogen bonds: with C[DOUBLE BOND]O urethane (possibly with ester group) and ether groups. An addition of poly[(R,S)-3-hydroxybutyrate] caused the slight increase in number of urethane-urethane hydrogen bonds. For some of polyurethanes (based on polyoxytetramethylenediol) the allophanate structures were present.
