What is Modified Polyisophthalamides Bearing Pendent Benzoylamino And/or (Phenylamino)carbonyl Groups about?

A series of modified polyisophthalamides were prepared from 5-(phenylamino)carbonyl-1,3-phenylenediamine and 5-benzoylamino-isophthalic acid. The polymers were characterized by FT-IR, 'H-NMR, inherent viscosity, water absorption measurements, x-ray, DTA, TGA, and isothermal gravimetric analysis. The modified polyamides were amorphous and softened at 210-245OC. They showed higher hydrophilicity and better solubility in certain solvents such as DMF, DMSO, CCl,COOH, cyclohexanone, and n-cresol than the corresponding unmodified polyamide. They started to lose weight at 329-344°C in N2 or air, whereas the degradation of unmodified polyamide started at 320°C in N, and 308°C in air.
