The purpose of this research was synthesis and electron beam modification of novel
ester elastomers consisting of sugar alcohol–succinic acid block and butylene glycol–succinic acid
block. Four di erent alditols were used in the synthesis—sorbitol, erythritol, xylitol, and glycerol.
The materials were irradiated with doses of 50, 100, and 150 kGy in order to determine which dose
is the most beneficial. As expected, irradiation of the materials has led to the cross-link density
becoming higher and improvement of the mechanical properties. Additionally, the materials were
also sterilized in the process. The great advantage of elastomers described in the paper is the fact
that they do not need chemical cross-linking agents or sensitizers in order to undergo radiation
modification. The following tests were performed on cross-linked poly(polyol succinate-co-butylene
succinate) elastomers: quasi-static tensile test, determination of cross-link density, di erential
scanning calorimetry (DSC), dynamic thermomechanical analysis (DMTA), wettability (water contact
angle), and Fourier transform infrared spectroscopy (FTIR). In order to confirm successful synthesis,
prepolymers were analyzed by nuclear magnetic resonance spectroscopy (1H NMR and 13C NMR).
