A set of novel aromatic polyamides containing pyridine pendent groups was prepared from aromatic diamines and new monomers that are 5-substituted derivatives of isophthalic acid bearing nicotinamide, isonicotinamide, or picolinamide groups. The polymers were obtained in high yield and high mol. weight by the phosphorylation method of polycondensation. They were characterized by spectroscopic and chromatog. methods and several of their properties were investigated. All of the polymers were soluble in polar aprotic solvents and gave films of good mech. properties. Glass transition temperatures were higher than that of the reference polymer, poly(m-phenyleneisophthalamide) (IP-MPD), while the thermal resistance, defined by the initial decomposition temperature observed by thermogravimetry, was in the range 370°-420°, lower by 30°-70° than that of IP-MPD. The presence of a pendent pyridine group and an addnl. amide side group per repeat unit made the polymers essentially amorphous and greatly improved their abilities to absorb water in comparison with nonsubstituted polyamides. Water uptake values up to 15% were observed at 65% relative humidity.
