Abstract

PURPOSE: To produce an aromatic polyester copolymer having excellent heat resistance, by reacting two specified classes of alkali metal salts of bisphenols with terephthaloyl chloride with the aid of a phase transfer catalyst.
CONSTITUTION: The titled copolymer containing repeating units of fomulasIand II, wherein Ar1 is a bivalent aromatic group, Ar2 is different from Ar1 and is a group of formula III, wherein R is a substituent and r is 0 or 1W4, at a ratio of formulaI/(formulaI+ formula II) is 0.2W0.8 (mol ratio). This copolymer can be prepared, for example, by reacting alkali metal salts of bisphenols represented by formula IV, wherein Y is a bivalent group selected from the group consisting of CH2, C(CH3)2, C(CF3)2, O, S, SO2 and CO, R' and R" are each a 1W4C alkyl, alkoxy or a halogen, p and q are each 0 or 1W4 and m and n are each 0 or 1, and by formula V, wherein R''' is defined as R' or R" and r is 0 or 1W4, with terephthaloyl chloride with the aid of a phase transfer catalyst (e.g., trioctylmethylammonium chloride).
