novel polyamides have been prepared in high yields by the polycondensation reactions of bis(;~-carboxypheny l)-and bis(4-carboxypheny l)phenylphosphine oxide with 3,3'-and 4,4'-diaminodipheny lsulfone. The thermal properties of these materials were studied using differential scanning calorimetry and
