Studies on synthesis and physico-chemical properties of some novel linear homopolyesters based on s-triazine

Eleven homopolyesters were synthesized by high temperature polycondensation of 2-(N-ethylanilino)-4,6-bis (phenoxy-2-carbonyl-chloride)-s-triazine [EAPCCT] with each of the following eleven diols: bisphenol-A (BPA), bisphenol-C (BPC), phenolphthalein (Ph), 1, 8-dihydroxyl anthraquinone (DHA-1,8), 1,4-dihydroxy anthraquinone (DHA-1,4), resorcinol (R), hydroquinone (Hq), catechol (C), ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG). All the polyesters were characterized by solubility, density, and viscosity measurements, IR spectroscopy and thermogravimetric analysis methods. All the polyesters were soluble at high temperature in acetone, dimethylformamide, dimethylsulphoxide, dimethylacetamide, etc. and have reduced viscosities in the range 0.486-0.699 dL/g in the dimethylformamide at 30 C. Homopolyesters derived from 1,4-dihydroxy anthraquinone showed greater thermal stability than the other polyesters.
