Abstract
PURPOSE:To provide an aromatic copolyester excellent in heat resistance, melt moldability, etc., by reacting a specified aromatic diol with an aromatic dicarboxylic acid and an aromatic hydroxy carboxylic acid at a specified molar ratio. CONSTITUTION:An aromatic diol of the formula: OH-Ar1-OH (wherein Ar<1> is a bivalent aromatic group, MW>=400, not containing any of phosphorus, sulfur and nitrogen atoms) (e.g., formula I or II) is reacted with an aromatic dicarboxylic acid (e.g., terephthalic acid) and an aromatic hydroxy carboxylic acid (e.g., 4-hydroxybenzoic acid) at a specified molar ratio. In this way, an aromatic random copolyester which consists of units of formulas III, IV and V (wherein Ar<2> and Ar<3> are each a bivalent aromatic group), in which units of formula III and units of formula IV are present in equimolar amounts, and the molar ratio of units of formula III to units of formula V is 5/95-95/5, and which has an intrinsic viscosity of 0.5 or above can be obtained.
