| Abstract: | A novel phosphorus-contained semi-aromatic polyamide was prepared from bis（3-aminophenyl）pheny phos-phine oxide（BAPPO）and hexanedioic acid by Yamazaki phosphorylation method. The main factors,such as reaction tem-perature,monomer concentration,solvent and reaction time were investigated. The inherent viscosity of the polymer was 0.47 dL/g. The structure of the polymer was characterized by FTIR and1H NMR. The results of DSC and TGA showed the polymer exhibited high glass transition temperature and good thermal stability（Tg=206,℃,T5%=388.1,℃）. The limited oxygen index of the thin film sample was 43%,which indicated that the polymer has excellent flame retardancy. |
