Abstract: 

Several homopolyesters were synthesized by high temperature polycondensation of 2-(N-piperidino)-4,6-bis(naphthoxy-2-carbonyl chloride)-s-triazine [PNCCT] with each of the eleven diols: bisphenol-A (BPA), bisphenol-C (BPC), phenolphthalein (Ph), 1, 5-dihydroxy anthraquinone (DHA-1,5), 1,4- dihydroxy anthraquinone (DHA-1,4), resorcinol (R), hydroquinone (Hq), catechol (C), ethyleneglycol (EG), diethyleneglycol (DEG) and triethyleneglycol (TEG). All the polyesters were characterized by solubility, density, viscosity measurements, IR spectra and thermogravimetric analysis. All the polyesters are soluble at high temperature in acetone, dimethylformamide, dimethylsulphoxide, dimethylacetamide, etc. The polymer has reduced viscosity in the range 0.522- 0.739 dL g-1 in dimethylformamide at 30oC. Homopolyesters derived from phenolphthalein showed greater thermal stability than other polyesters.
