A series of copolyesters has been synthesized by polycondesation of 2-(N-piperidino)-4,6-bis (2-napthoxy, 6-carbonyl chloride)-s-triazine [PNCCT] with various mixture of diols, such as [Hq + BPA], [C + BPA], [R + BPA], [C + BPC], [R + BPC], [BPC + BPS], [Hq + Ph], [Hq + C], [Hq + BPS] and [Hq + Eg]. All the synthesized copolyesters were characterized by solubility, density, viscosity, IR, 1H NMR and TGA spectra. Modification and introduction of bulky pendent group in monomer structure is increases the thermal stability and solubility of the polymers. The density of all the copolyesters varies from 1.204 to 1.165 g/cm3. The intrinsic viscosity, reduced viscosity and inherent viscosity were determined by using Huggins & Kraemer method. The activation energy was calculated by Broido and Horowitz & Metzger method for PE 8 (II) and PE 9 (II) were found 21.30 and 18.69 kcal/mol respectively. The synthesized polymers are found to stable more than 300 ?C temperature so it can be used for high temperature applications.
