Abstract Biobased urea nowadays attracts increasing attention as a biomass resource with giant potential, which benefits from the development of biobased ammonia and ecological sanitation system. Urea is an ideal feedstock for chemical industry and developing new urea-based pol ymer materials can take advantage of the urea resource. In this work, a class of renewable linear polyesters, nam ely polyisocyanuratoesters (PICEs) were synthesized from a urea-based monomer bis(2-carbomethoxyethyl) isocyanurate and biobased aliphatic diols. Compared with conventional aliphatic polyesters, PICEs containing isocyanurate rings in the polymer chain backbone exhibit outstanding flame retardancy that both PICE-4 (the number More >
