title = "Thermal stability and flame retardance of novel thermoplastic poly(imide-urethane)",
abstract = "A kind of novel thermoplastic poly(imide-urethane) (TPIU) was synthesized through combining pyromellitic dianhydride (PMDA) into normal polyurethane. Further, hydroxyl terminated polydimethylsiloxane (PDMS) was inserted into the TPIU chain to form thermoplastic TPIU-PDMS. The chemical structures of TPIU and TPIU-PDMS are shown in Schemes (I) and (II). In thermal stability, TPIU of the imide group has higher thermal decomposition temperature than commercial thermoplastic polyurethane (TPU) according to the TGA analysis. The total heat released (THR) and peak heat release rate (p-HRR) of TPIU were lower than those of the TPU by 14.62 % and 64.02 %, respectively, based on cone calorimeter testing. TPIU-PDMS showed good thermal stability by TGA. The cone calorimeter testing showed that TPIU-PDMS could reduce THR and p-HRR values compared with the TPIU with the only imide group, meaning the improved flame retardancy because of coexistence of the imide and dimethylsiloxane groups in the chain.",
