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 CO 2 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.
