New biobased polyurethanes were synthesized from cyclocarbonated broccoli seed oil and different di- or triamines. The isocyanate-free route to synthesize these polyurethanes was divided into three steps: the broccoli seed oil was first epoxydized, then carbonated with CO2 at a pressure of 50 bar to convert oxiranes into cyclic carbonates, and finally polyurethanes were prepared through the reaction of the cyclocarbonated oil with three different di- or triamines, that is, butylene diamine, m-xylene diamine, and bis(hexamethylene triamine). The chemical reactions were monitored by Fourier transform infrared spectroscopy, nuclear magnetic resonance, and electrospray ionisation mass spectrometry and mechanical properties of thus-prepared polyurethanes were determined by dynamic mechanical analysis and tensile characterization. An UV-responsive material was finally prepared from butylene diamine based polyurethane integrating phosphorescent molybdenum nanoclusters. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
