Sulfone-containing polyesters of 18 kinds having inherent viscosities of 1.19-0.16 dL g-' were prepared derived from 4,4'-sulfonyl dibenzoyl chloride by solution polycondensation from various aromatic and aliphatic diols in nitrobenzene at 82Β°C. The polyesters were examined with IR spectra, inherent
