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 82ยฐC. The polyesters were examined with IR spectra, inherent

Aluminum oxide coated cellulose fibers were modified, by an impregnation procedure, with n-propylpyridinium chloride silsesquioxane polymer. Good adherence of the polymer to the surface of modified cellulose fibers was obtained due to the Al-O-Si bond formation. The metal X-ray mapping showed that a
