AbstractPoly(urea-urethane)s (PUUR), wherein the polyol substrates of petrochemical origin, partly replaced by vegetable polyols, were synthesized. Various contents of polyols derived from rapeseed oil – from 0 to 50 wt % were used. In order to determine the chemical structure of the obtained samples, they were exam¬ined using Fourier transform infrared spectroscopy (FT-IR). Physicochemical and mechanical properties were determined using, among others, methods of differential scanning calorimetry (DSC) and dynamic mechani¬cal analysis (DMA), as well as the tribological tests were performed. Studies have shown that new material obtained using the highest content of the polyol of vegetable origin (50 wt %) was characterized by the best storage modulus and friction coefficient. This material can be applied where low abrasive wear and volume resistivity is required.
