Notes:
Aromatic polyamides were synthesized by the low-temperature solution polycondensation of 9,10-dihydro-9,10-o-benzeno-1,5-anthracenediamine (2,7-triptycenediamine) with aromatic diacyl dichlorides. All the polycondensations proceeded in quantitative yields. The obained aromatic polyamides have high inherent viscosities (ca. 1,04-3,24 dL/g). They are soluble in various organic solvents such as 1-methyl-2-pyrrolidone (NMP). The polyamides show high glass transition temperatures (Tg ≈ 337-370°C) and high decomposition temperatures (ca. 446-486°C at 5% weight loss). In particular, the polyamide prepared from the diamine and 4,4′-sulfonyldibenzoyl dichloride not only was soluble in dimethyl sulfoxide, N,N-dimethylformamide, hexamethylphosphoric triamide, NMP, N,N-dimethylacetamide and pyridine, but also showed high Tg (370°C).
