Summary

Poly(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 50wt% were used. In order to determine the chemical structure of the obtained samples, they were examined using Fourier transform infrared spectroscopy (FT-IR). Physicochemical and mechanical properties were determined using, among others, methods of differential scanning calorimetry (DSC) and dynamic mechanical 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.
