A new series of copoly(ester-thioester)s had been synthesized using direct polycondensation technique. These copolythioesters were synthesized by direct polycondensation of 4,4'-(tereph-thaloyIdithio) diacetic acid I, 3,3'(isophthaloyl-dithio) diacetic acid II, or 1,8 (sebacoyldithio) diacetic acid III, with 2,6-bis(p-hydroxybenzylidene) tert. butyl cyclohexanone IV and 2,6-divanyli-dene tert. butyl cyclohexanone V, using a condensing agent consisting of pyridine-thionyl clhloride complex. The resulting copolymers were characterized by elemental and spectral analyses, solubility, viscometery, electronic spectra and thermogravimietric analyses. The crystallinity of some copolymers was examined by X-ray diffraction analyses. Furthermore, the morphology of selec ted examples of the copolymers was examined by scanning electron microscopy.
