A general method for the preparation of aromatic poly(ether-sulfone-amide)s has been developed. Polymerization is based on the palladium-catalyzed polycondensation of aromatic dibromides containing ether sulfone structural units, aromatic diamines, and carbon monoxide. Reactions 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 gave a series of poly( ether-sulfone-amide)s with inherent viscosities up to 0.86 dL/g under mild conditions. The polymers were quite soluble in strong acids, 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 470 degrees C in air. The glass transition temperatures of the polymers were around 230 degrees C, which are higher than those of poly(ether-sulfone) analogues. These polymers also showed the good tensile strengths and tensile modulus.
