Abstract: PURPOSE:To prepare an arom. polyester contg. no residual catalyst by melt polymerizing a mixture of an arom. dicarboxylic acid with a diol in the presence of an electron-donating amine catalyst. CONSTITUTION:An arom. polyester contg. no residual amine is prepd. by melt- polymerizing a mixture of an arom. dicarboxylic acid and its deriv. with a diol and its deriv. in the presence of an electron-donating amine catalyst. The structure of pref. bisphenols and their functional derivs. is shown by the formula, wherein X is O, S, SO2, SO, CO, 1-4C alkylene, or 1-4C alkylidene; and R1 to R4 and R'1 to R'4 are each H, halogen, or 1-4C alkyl. Among the above- mentioned bisphenols, 2,2-bis(4'-hydroxyphenyl)propane (trivial name: bisphenol A) is most easily available and most widely used. Pref. examples of the electron- donating amine catalyst are activated pyridine compds., imidazoles, and alicyclic amine compds.
