Aromatic poly(ether-ketone-amide)s were prepared by the palladium-catalyzed polycondensation of aromatic dibromides containing ether ketone units, aromatic diamines, and carbon monoxide. Polymerizations were carried out in N,N-dimethylacetamide (DMAc) in the presence of palladium catalyst, triphenylphosphine, and 1,8-diazabicyclo [5,4,0]-7-undecene (DBU), and resulted in poly (ether-ketone-amide) s with inherent viscosities up to 0.82 dL/g under mild conditions. The polymers were quite soluble in strong acid, dipolar aprotic solvents, and pyridine. Thermogravimetry of the polymers showed excellent thermal stability, indicating that 10% weight losses of the polymers were observed in the range above 400-degrees-C in nitrogen atmosphere. The glass transition temperatures of the polymers were about 200-degrees-C, which are higher than those of poly(ether-ketone) analogues. These polymers also showed good tensile strength and tensile modulus.
