【摘要】 |
High-molecular-weight polyarylene sulfide sulfone amide (PASSA) and polyarylene sulfide ketone amide (PASKA) were synthesized from diamine monomers containing sulfone or ketone group by a low temperature solution polycondensation reaction in anhydrous 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 0.72 dL/g in NMP (PASSA) and 0.62 dL/g in H2SO4 (PASKA) at 30±0.1°C, respectively. The polymers possess excellent thermal properties with the glass transition temperature (Tg) for PASSA and PASKA are 274.9°C and 195.2°C, respectively. The initial degradation temperatures (Ti) for PASSA and PASKA are 461.55°C and 467.08°C, 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. |
