Abstract
PURPOSE: To improve the stability and the heat resistance of a polyester, e.g., polybutylene terephthalate, etc., by adding a small amount of an organotin compound to the polyester at a specific reaction stage.
CONSTITUTION: Esterification or ester exchange reaction of a dicarboxylic acid (lower alkyl ester) component consisting mainly of aromatic dicarboxylic acids, with an alkylene glycol component consisting mainly of 1, 4-butanediol, is carried out in the presence of an organotitanium compound of a catalyst amount. Thereafter preferably 0.01W0.05 mole% (on the basis of the recurrent unit of the polyester) of an organotin compound, e.g. dibutyltin oxide, etc., is incorporated at the stage after the polycondensation for the production of the polyester.
