Abstract: A series of fluorine-containing polyurethane elastomers (FPUEs) were synthesized from 2,2-bis[4-(4-amino-2-trifluoromethylphenoxy)phenyl] hexafluoropropane (BAFPF(6)P), which was made from 2-chlorobenzotrifluoride and 2,2-bis(4-hydroxyphenyl) hexafluoropropane and characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, thermogravimetric analysis, microscale combustion colorimeter and contact angle measurement. The results show that the fluorine-containing polyurethane elastomers prepared from BAFPF(6)P have good thermal stability and low surface tension. Furthermore, fluorine-containing polyurethane elastomers also exhibit good flame retardance and the peak heat release rate and total heat released of fluorine-containing polyurethane elastomer based on BAFPF(6)P are much lower than those of polyurethane elastomer without the fluorine element.
