The goal of this research was developing biodegradable and biocompatibile xylitol-based copolymers with improved mechanical properties, and investigating the change in their thermal and chemical properties with progress of the cross-linking process. Using a raw material of natural origin such as xylitol, a prepolymer was obtained by esterification and polycondensation. Then, at subsequent stages of the crosslinking process in a vacuum dryer, samples of materials were taken to determine the progress of the process using Fourier transform infrared spectroscopy. The method of differential scanning calorimetry also defined changes in the ranges of phase changes occurring at each stage of the crosslinking process. After the crosslinking process, ester materials based on sebacic and succinic acid were characterized in terms of mechanical and surface properties.
