"An intrinsically halogen-free flame retardant polyamide 66 (FR-PA66) was fabricated successfully by two-step polymerization reaction with adipic acid hexamethylene salt (AH salt) and bis(4-carboxyphenyl) phenyl phosphine oxide (BCPPO) as raw materials. The structure, combustion properties and thermal stability were characterized by means of intrinsic viscosity, Fourier transform infrared spectroscopy (FTIR), combustion testing, differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and scanning electron microscope (SEM)," scientists in Taiyuan, People's Republic of China report.
"Experiments show that BCPPO have excellent copolymerization ...
