EJeven 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: bisphenoJ-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, dimethyl acetamide, etc. and have reduced viscosities
in the range 0.486-0.699 dUg in the dimethylformamide at 30°C. Homopolyesters
derived from 1,4-dihydroxy anthraquinone showed greater thermal stability than the other
polyesters.
