Abstract

PURPOSE: To obtain a polyester excellent in color and moldability, by reacting a terephthalic acid-based dicarboxylic acid with a glycol in the presence of p-hydroxybenzoic acid.
CONSTITUTION: In producing a polyester by reacting a terephthalic acid-based dicarboxylic acid or its esterifiable derivative with a glycol or its esterifiable derivative; there is added, at any stage before completion of the polyester production, p- hydroxybenzoic acid and/or its esterifiable derivative in an amount of 0.01W 15mol%, based on the dicarboxylic acid component. As the dicarboxylic acid, terephthalic acid is chiefly used. Preferred esterifiable derivatives are 1W4C lower alkyl esters and phenyl esters, and part of the ester can be replaced with another dicarboxylic acid such as isophthalic acid, phthalic acid, naphthalenecarboxylic acid or adipic acid.
