Abstract
A process for producing aromatic polyester which comprises mixing PA0 5 to 70 mol % (as calculated by converting the repeating unit mentioned below into one molecule) of polyester (A) with the repeating unit represented by general formula (I), ##STR1## and 95 to 30 mol % of an acyloxyl aromatic carboxylic acid (B), with 0.1 to 20 mol % based on the total amount of (A) and (B), of a diacyloxy aromatic compound (C) represented by general formula (II), ##STR2## and reacting the resulting mixture. The aromatic polyester is excellent in elasticity and mechanical strength, as well as toughness.
