| dc.description | A novel method for the synthesis of copoly(ester-thioester)s of high molecular weight has been developed. These polymers were prepared readily by direct polycondensation of 4,4′-(terephthaloyldithio) diacetic acid I, 3,3′(isophthaloyldithio) diacetic acid II, or 1,8 (sebacoyldithio) diacetic acid III, with 2,6-bis(p-hydroxybenzylidene) cyclohexanone IV, and 2,6-divanillylidenecyclohexanone V, using a condensing agent consisting of a pyridine-thionyl chloride complex. The resulting polymers were characterized by elemental and spectral analyses, solubility, viscometry, differential scanning calorimetry and thermogravimetric analyses. The crystallinities of all the polymers were examined by X-ray diffraction. Several physical and thermal characteristics were correlated with their chemical structures. |
