Certain structurally modified polyisophthalamides with bulky azo pendent groups were prepared from the polycondensation of 5-(4-dimethylaminoazobenzene) isophthaloyl chloride with various aromatic diamines. The corresponding unmodified polyisophthalamides were also synthesized to compare their prope

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
Polyisophthalamides were prepared from aromatic diamines and 5-iminobenzoylisophthalic acid by the Yamazaki method of direct polyamidation catalyzed by triphenylphosphite. The properties of the polymers were measured and compared with the analogous unsubstituted polyisophthalamides. The incorporatio
