主　　题：Urea isocyanurate ring aliphatic diol linear polyester flame retardancy 

摘      要：Biobased urea nowadays attracts increasing attention as a biomass resource with giant potential,which benefits from the development of biobased ammonia and ecological sanitation *** is an ideal feedstock for chemical industry and developing new urea-based polymer materials can take advantage of the urea *** this work,a class of renewable linear polyesters,namely polyisocyanuratoesters(PICEs)were synthesized from a urea-based monomer bis(2-carbomethoxyethyl)isocyanurate and biobased aliphatic *** with conventional aliphatic polyesters,PICEs containing isocyanurate rings in the polymer chain backbone exhibit outstanding flame retardancy that both PICE-4(the number‘4’refers to the number of methylene in diols,e.g.4 for butylene and 6 for hexylene)and PICE-6 have high limiting oxygen index values over 30%.In the UL 94 tests,PICE-6 reaches V-1 rating;while V-2 is found for *** PICEs exhibit similar pyrolysis behavior that the temperatures of 5%weight loss are around 320°*** are found to have glass transition among 20°C-45°*** crystallization behavior is observed without annealing except for PICE-10,which can crystallize even at room temperature.
