Abstract
Aromatic polyesters from bisphenols and terephthaloyl chloride have been synthesized by interfacial polycondensation using immiscible binary solvents such as adiponitrile (AN)–carbon tetrachloride (CCl4) or ethylene glycol (EG)–CCl4 systems. Yields and solution viscosities of the resulting polyesters increased with increasing concentration of monomers in binary solvents and a high-molecular-weight polyester was obtained from bisphenol A in a solvent system of AN–CCl4. Partition coefficients of bisphenols in binary solvents had no influence on either yields or solution viscosities of the resulting polyesters. Copolyesters from bisphenol A and resorcinol have been synthesized by the same method.
