Abstract
PURPOSE: To prepare a polyester copolymer having high rigidity and heat resistance, and excellent color tone, by the esterification reaction of a dicarboxylic acid component containing diphenyl-4,4'-dicarboxylic acid with a diol component in the presence of K and/or Na compounds.
CONSTITUTION: The esterification reaction of a dicarboxylic acid component composed of 40W80mol% of diphenyl-4,4'-dicarboxylic acid and 60W20mol% of other aromatic dicarboxylic acid (or its ester-forming derivative) and a diol component composed of an alkylene glycol, is carried out in the presence of 10W350ppm, pref. 20W200ppm of K and/or Na compounds (as K and/or Na atom based on diphenyl- 4,4'-dicarboxylic acid) at a molar ratio of the diol component to the dicarboxylic acid component of 1.2W2.0, and the esterification product is subjected to polycondensation to obtain the objective polyester.
