Abstract: 

Thirteen linear aliphatic-aromatic polyesters were synthesized by interfacial polycondensation of various diacid chlorides such as adipoyl chloride (ADCL) and sebacoyl chloride (SECL) with various diols such as bisphenol-A (BPA), resorcinol (RES), 1,5-dihydroxy naphthalene(15DHN), 4,4’-bis(hydroxyl)benzilidine aniline (BHBA), 4,4’-bis(hydroxybenzilidine)benzidine(BHBB), 4,4’-bis(hydroxybenzilidine)-p- phenylenediamine (BHBP), 4,4’-bishydroxy biphenyl thioether (BHBPT) using chloroform-water interphase system, alkali as an acid acceptor and citramide as phase transfer catalyst at ambient temperature. The resulting polyesters were characterized by solubility test, elemental analysis, intrinsic viscosity measurements, FT-IR, and 1H-NMR spectral analysis, and thermo gravimetric analysis.
