A new interesting class of linear unsaturated polycarbonates based on 2,5-bis(p-hydroxybenzylidene) cyclopentanone I, 2,5-divanillylidenecyclopentanone II, 2,6-bis(p-hydroxybenzylidene) cyclohexanone III, 2,6-divanillylidenecyclohexanone IV and 2,7-bis(p-hydroxybenzylidene) cycloheptanone V have been prepared. An inter-facial phosgenation technique carried out at ambient temperature was used for the synthesis of the polycarbonates. The resulting polycarbonates were characterized by elemental analyses, infrared spectroscopy, <sup>1</sup>H nuclear magnetic resonance spectral analyses, viscometry, differential scanning calorimetry and thermogravimetric analysis measurements. The majority of the polycarbonates were soluble in halogenated solvents. The crystallinity of all the polymers was examined by X-ray analysis. In addition, the electrical properties of the polycarbonates were tested. Furthermore, the morphology of selected examples of the polycarbonates was examined by scanning electron microscopy. |
