High-molecular-weight polyarylene sulfide sulfone amide (PASSA) and polyarylene sulfide ketone amide (PASKA) were synthesized from diamine mono-mers containing sulfone or ketone group by a low temperature solution polycondensation reaction in anhy-drous N-methylpyrrolidone (NMP). The structures of the monomers and corresponding polymers were identified by IR-spectra and UV spectra. The maximum intrinsic viscosities of the polymers were 0.72dL/g in NMP (PASSA) and 0.62 dL/g in H2SO4 (PASKA) at 30±0.1℃,respectively. The polymers possess excellent thermalproperties with the glass transition temperature (Tg) for PASSA and PASKA are 274.9℃ and 195.2℃, respec-tively. The initial degradation temperatures (T i) for PASSA and PASKA are 461.55℃ and 467.08℃, respectively,which suggests that PASSA and PASKA are excellent heat-resistant materials. The dissolvability experiments show that PASSA and PASKA are also corrosion resistance materials.
